1 Evaluation Module Overview
1.1 Introduction
The LM5185-Q1 single-isolated-output (SIO) evaluational module (EVM), otherwise known as LM5185EVM-SIO,
is designed to demonstrate the features and functionality of the LM5185-Q1 device. The device is a 100-VIN
Primary-Side-Regulated (PSR) flyback DC/DC controller based on sampling the primary winding voltage of the
transformer to achieve tight output regulation and high efficiency, without using the opto coupler nor tertiary bias
winding like in a conventional flyback converter.
This user's guide describes the characteristics and operation of the evaluataion module LM5185EVM-SIO.
This document provides examples and instructions on how to use the evaluation module, and presents typical
performance curves and key waveforms. Throughout this document, the terms of evaluation board, evaluation
module, and EVM are synonymous with the LM5185EVM-SIO. This document also includes a schematic,
reference printed circuit board (PCB) layout, and a complete bill of materials (BOM).

1.4 Device Information
The factory default settings of the EVM allow the operation with an input voltage range from 20 V to 60 V. The
device produces a single isolated output voltage of 16.4 V ±1% @ 1 A load, and achieves > 90% peak efficiency.
Fine-tuning of the output voltage can be realized by adjusting the external resistor values at the FB pin. In
addition, the users can modify the EVM to enable the operation under a VIN down to 6 V with derated output
current of 0.4A by changing the EN/UVLO set point. Further lower input voltage down to 4.5V is supported by
the LM5185-Q1 but the EVM requires a different transformer. However, the maximum VIN voltage of the EVM
can be increased to 90 V if the power MOSFET is changed to a 150 V or higher rated device, and if the input
bulk capacitor is replaced with at least a 100 V rated part. Multiple isolated output can also be supported by the
LM5185-Q1 but requires a different transformer. Please refer to the Quick Start Design Calculator to help design.
Refer to TI product data sheet SNVSBT4 for more detailed information of the LM5185-Q1 PSR flyback controller.

Figure 2-1. EVM Test Setup
The test setup consists the following instruments in addition to the EVM board.
•Power Supply: The input dc voltage source capable of at least 0-80-V and 2 A.
•Load: The load must be electronic constant-resistance (CR) or constant-current (CC) mode load, capable of
0 Adc to 2 Adc up to 20 V. For a no-load input current measurement, disconnect the electronic load as the
load can draw a small residual current.
•Multimeters:
–Voltmeter 1: Input voltage at VIN+ to VIN–. Set voltmeter to an input impedance of 100 MΩ.
–Voltmeter 2: Output voltage at VOUT+ to VOUT-. Set voltmeter to an input impedance of 100 MΩ.
–Ammeter 1: Input current. Set ammeter to 1-second aperture time.
–Ammeter 2: Output current. Set ammeter to 1-second aperture time
•Oscilloscope: With the scope set to 20-MHz bandwidth and AC coupling, measure the output voltage ripple
directly across an output capacitor with a short ground lead normally provided with the scope probe. Place
the oscilloscope probe tip on the positive terminal of the output capacitor, holding the ground barrel of the
probe through the ground lead to the negative terminal of the capacitor. TI does not recommend using
a long-leaded ground connection because this can induce additional noise given a large ground loop. To
measure other waveforms, adjust the oscilloscope as needed.

2.4 Assembly Instructions
Refer to Section 2.5 of this user's guide for the important notice on safety concerns when handling the EVM. The
following are the recommended instructions for the EVM test setup assembly.
Input Connections
• Prior to connecting the DC input source, set the current limit of the input supply to 100 mA maximum. Verify
the input source is initially set to 0 V and connected to the VIN+ and VIN– connection points, as shown in
Figure 2-1. An additional input bulk capacitor is recommended to provide damping if long input lines are used.
• Connect Voltmeter 1 at VIN+ and VIN– connection points to measure the input voltage.
• Connect Ammeter 1 to measure the input current and set to at least 1-second aperture time.
Output Connections
• Connect electronic load to VOUT+ and VOUT- connection points as shown in Figure 2-1. Set the load to
constant-resistance mode or constant-current mode at 0 A before applying input voltage.
• Connect Voltmeter 2 at VOUT+ and VOUT- connection points to measure the output voltage.
• Connect Ammeter 2 measure the output current.
Test Procedure
• Set up the EVM as described above.
• Set load to constant resistance or constant current mode and to sink 10 mA.
• Increase input source from 0 V to 20 V; use voltmeter 1 to measure the input voltage.
• Increase the current limit of the input supply to 1000 mA.
• Use voltmeter 2 to measure the output voltage, vary the load from 10 mA to 1000 mA DC; VOUT must
remain within the load regulation specification.
• Set the load current to 500 mA (50% rated load) and vary the input source voltage from 20 V to 60 V; VOUT
must remain within the line regulation specification.
• Use the oscilloscope to probe different signals of interest. Be careful of the probe ground reference.
• Decrease load to 10 mA. Decrease input source voltage to 0 V.
• Shut down both the input source and load, and then the voltmeters and ammeters.
2.5 Best Practices
Please take caution when handling the EVM. Operating the EVM board with up to 60 VIN can generate >75 V
voltage at certain circuit nodes as marked by the high voltage symbol on the PCB. Operating the EVM board
with the maximum load can generate hot spots in certain areas of the PCB as marked by the hot surface
symbols. Please read the following notices carefully.

Always follow TI’s set-up and application instructions, including use of all interface components within their
recommended electrical rated voltage and power limits. Always use electrical safety precautions to help ensure
your personal safety and the safety of those working around you. Contact TI’s Product Information Center http://
support.ti.com for further information.
Save all warnings and instructions for future reference.
Failure to follow warnings and instructions can result in personal injury, property damage, or death due
to electrical shock and/or burn hazards.
The term TI HV EVM refers to an electronic device typically provided as an open framed, unenclosed printed-
circuit board assembly. It is intended strictly for use in development laboratory environments, solely for qualified
professional users having training, expertise, and knowledge of electrical safety risks in development and
application of high-voltage electrical circuits. Any other use and/or application are strictly prohibited by Texas
Instruments. If you are not suitably qualified, you should immediately stop from further use of the HV EVM.
•Work Area Safety:
– Maintain a clean and orderly work area.
– Qualified observers must be present anytime circuits are energized.
– Effective barriers and signage must be present in the area where the TI HV EVM and interface electronics
are energized, indicating operation of accessible high voltages can be present, for the purpose of
protecting inadvertent access.
– All interface circuits, power supplies, evaluation modules, instruments, meters, scopes, and other related
apparatus used in a development environment exceeding 50 VRMS/75 VDC must be electrically located
within a protected Emergency Power Off (EPO) protected power strip.
– Use a stable and non-conductive work surface.
– Use adequately insulated clamps and wires to attach measurement probes and instruments. No freehand
testing whenever possible.
•Electrical Safety:
As a precautionary measure, it is always a good engineering practice to assume that the entire EVM can
have fully accessible and active high voltages.
– De-energize the TI HV EVM and all inputs, outputs, and electrical loads before performing any electrical or
other diagnostic measurements. Confirm that TI HV EVM power has been safely de-energized.
– With the EVM confirmed de-energized, proceed with required electrical circuit configurations, wiring,
measurement equipment hook-ups, and other application needs, while still assuming the EVM circuit and
measuring instruments are electrically live.
– When EVM readiness is complete, energize the EVM as intended.
WARNING
WARNING: While the EVM is energized, never touch the EVM or its electrical circuits as
the EVM and circuits can be at high voltages capable of causing electrical shock hazard.
•Personal Safety:
– Wear personal protective equipment, for example, latex gloves and/or safety glasses with side shields or
protect EVM in an adequate lucent plastic box with interlocks from accidental touch.
•Limitation for Safe Use:
– EVMs are not to be used as all or part of a production unit.
Safety and Precautions
The EVM is designed for professionals who have received the appropriate technical training, and is designed
to operate from an AC power supply or a high-voltage DC supply. Please read this user guide and the safety-
related documents that come with the EVM package before operating this EVM.

2.1 These terms do not apply to Software. The warranty, if any, for Software is covered in the applicable Software License
Agreement.
2.2 TI warrants that the TI EVM will conform to TI's published specifications for ninety (90) days after the date TI delivers such EVM
to User. Notwithstanding the foregoing, TI shall not be liable for a nonconforming EVM if (a) the nonconformity was caused by
neglect, misuse or mistreatment by an entity other than TI, including improper installation or testing, or for any EVMs that have
been altered or modified in any way by an entity other than TI, (b) the nonconformity resulted from User's design, specifications
or instructions for such EVMs or improper system design, or (c) User has not paid on time. Testing and other quality control
techniques are used to the extent TI deems necessary. TI does not test all parameters of each EVM.
User's claims against TI under this Section 2 are void if User fails to notify TI of any apparent defects in the EVMs within ten (10)
business days after delivery, or of any hidden defects with ten (10) business days after the defect has been detected.
2.3 TI's sole liability shall be at its option to repair or replace EVMs that fail to conform to the warranty set forth above, or credit
User's account for such EVM. TI's liability under this warranty shall be limited to EVMs that are returned during the warranty
period to the address designated by TI and that are determined by TI not to conform to such warranty. If TI elects to repair or
replace such EVM, TI shall have a reasonable time to repair such EVM or provide replacements. Repaired EVMs shall be
warranted for the remainder of the original warranty period. Replaced EVMs shall be warranted for a new full ninety (90) day
warranty period.
WARNING
Evaluation Kits are intended solely for use by technically qualified,
professional electronics experts who are familiar with the dangers
and application risks associated with handling electrical mechanical
components, systems, and subsystems.
User shall operate the Evaluation Kit within TI’s recommended
guidelines and any applicable legal or environmental requirements
as well as reasonable and customary safeguards. Failure to set up
and/or operate the Evaluation Kit within TI’s recommended
guidelines may result in personal injury or death or property
damage. Proper set up entails following TI’s instructions for
electrical ratings of interface circuits such as input, output and
electrical loads.
NOTE:
EXPOSURE TO ELECTROSTATIC DISCHARGE (ESD) MAY CAUSE DEGREDATION OR FAILURE OF THE EVALUATION
KIT; TI RECOMMENDS STORAGE OF THE EVALUATION KIT IN A PROTECTIVE ESD BAG.
