LM36010EVM User Guide
The Texas Instruments LM36010EVM evaluation module (EVM) helps designers evaluate the operation
and performance of the LM36010 Synchronous-Boost Single-LED Driver with 1.5-A High-Side Current
Source. The device offers configurability via I2C-compatible interface. It can be enabled in flash or torch
mode via the I2C interface or externally using the STROBE pin. The module utilizes one LED (D1)
mounted on the EVM.
The EVM contains one synchronous boost, single-LED flash driver (see Table 1).

1 Setup
This section describes the jumpers and connectors on the EVM as well as how to properly connect, set
up, and use the LM36010EVM.
1.1 Input/Output Connector Description
VINL, GND (Banana Connectors) – These are the power input terminals for the driver and provide a
power (VINL) and ground (GND) connection to allow the user to attach the EVM to a cable harness.
TP1 (Test Point) – This pin can be used to measure the input voltage VIN.
VINL, VIN (Jumper J2) – The user can monitor the inductor current and input current waveforms by
omitting this jumper and using separate wires from the power supply to the VINL and VIN pins. This will
remove the input capacitors from the inductor and eliminate their filtering effect to the inductor current.
STROBE (Jumper J3) – STROBE is an active high hardware flash enable. This pin can be used to
monitor the STROBE signal.
PWM, STROBE, GND (Jumper J4) – This jumper provides an external method for initiating a flash event.
The STROBE pin is connected to ground via a 300-kΩresistor internal to the LM36010EVM. To externally
drive this pin, either connect a control signal directly to the STROBE pin of the connector or place a
jumper between the pins STROBE (J4<2>) and PWM (J4<1>). PWM can be configured as a time-
adjustable voltage pulse via the General User Interface (GUI) software provided or can be driven
externally using a function generator.
Figure 1. STROBE Jumper Settings
VOUT (Jumper J5) – This pin can be used to measure the output voltage.
VOUT, VLED (Jumper J6) – This jumper provides access to the regulated output of the driver and the
output of the LED current sources. The user can measure VOUT with reference to GND, VLED with
reference to GND, and current source headroom directly between VOUT and VLED.
GND (Jumpers J8, J9, and J10) – These are additional pins to connect to ground (GND).
VLED, D1A (Jumper J11) – Connect VLED (J11<1>) and D1A (J11<2>) to light the LED as it connects
the LED output of the driver to the on-board anode of the flash LED.
VIO (Jumper J12) – This pin can be used to measure the VIO.
3.3V, VIO, VIN (Jumper J13) – This jumper provides pullup for the I2C lines (clock and data). VIO
(J13<2>) can be connected to the 3.3-V pin (J13<1>) of the TI LaunchPad™. Communication via the I2C
interface may not be possible if the supply voltage to the LED driver is below approximately 3 V.

LM36010EVM User Guide
LED Current Measurements, D1F, D1S, GNDS (Jumper J14) – The LM36010EVM provides a way to
accurately measure the LED current through the LED on board. Resistor R4 (0.1 Ω) is placed between the
cathode of LED (D1F) and ground. The user can first measure the resistor value accurately by first
applying a known current through force pin (D1F) and ground and measuring the voltage between sense
pin (D1S) and GNDS. Then, during normal flash or torch operation, the voltage measured across the
resistor divided by the resistor value will equal the current through the resistor (or the LED).
Figure 3. LED Current Measurements Jumper
SDA / SDK (Pins 9 and 10 on Launchpad) – These connections allow the user to externally control the
I2C lines.

Configuration of LM36010EVM jumpers is as shown in Figure 4.

LM36010EVM User Guide
The input voltage range for the flash driver is 2.5 V to 5.5 V. The on-board LED or an LED module should
be connected for proper operation.
The LM36010EVM dissipates power, especially during high current and long duration flash events. Power
will also be dissipated on the flash LEDs. TI recommends that in order to prevent overheating, repeated
flash events in very short time intervals is avoided. Special care must be taken with regards to thermal
management when using time-out values greater than 500 ms.
The EVM layout is designed to minimize temperature rise during operation. Depending on the PCB layout,
input voltage, and output current, it is possible to have the internal thermal shutdown circuit trip prior to
reaching the desired flash time-out value. A warning is also placed on the EVM as a safety measure.
Figure 5. LED Warning
For proper operation of the LM36010EVM, the jumpers should be properly configured. The recommended
setting using shorting blocks is:
• VIO (J13<2>) to 3.3 V (J13<1>) if TI Launchpad is used
• STROBE (J4<2>) to PWM (J4<1>) or external signal
• VLED (J11<1>) to D1A (J11<2>)
Texas Instruments has created LaunchPad (MSP432) and an I2C-compatible graphical user interface
(GUI) that can help exercise the part in a simple way. A description of how to install and use the
LaunchPad and the GUI is contained in Section 2 and Section 3.
The LM36010EVM has the means to “plug into” the LaunchPad BoosterPack connectors, which provide
the control signals for the simple interface. Power to the part needs to be provided externally. A USB
cable provided in LaunchPad MSP432 kit should be connected to the LaunchPad board from a PC as
shown in Figure 6.

2.1 Setup Overview
1. Verify jumper configuration on the MSP-EXP432P401R LaunchPad and the LM36010EVM as in
Figure 7 and Figure 4, respectively.
2. Connect the LM36010EVM to the MSP-EXP432P401R LaunchPad.
3. If using the MSP432 for the first time, install XDS110 drivers as in Section 2.2.
4. If the LM3601x GUI is not installed, refer to section Section 2.3.
5. Run the EVM software and select LM36010 button in the EVM selection pop-up window.
6. If the LaunchPad is new or was used for another purpose, EVM software asks to update firmware,
which can be done by clicking "FW Update" in the File menu on the top. EVM software restarts after
updating firmware.
7. For LM36010EVM operation with the GUI, refer to Section 3.

The register view is shown when “Register” icon is clicked, and it provides the Register values, FieldView
and Description fields. The user can enter the desired hex value to the registers in the “Value” column of
Register values or in the "Value" column of FieldView, or can also perform a bit-wise configuration of any
register fields by double-clicking on the corresponding register bit. "FieldView" displays the description of
all fields of the selected register. Each register can be read independently or all registers can be read at
once by utilizing the “Read” and “Read All” buttons, respectively.
The data is written to the register(s) in one of two ways, depending on the “Update Mode” field selection.
In "Immediate" mode, the register data is written immediately following a “Value”, an individual bit, or a
"Value" change. In “Deferred” mode, the displayed data is written to all registers upon depression of the
“Write” button. The “Read All” button can be pressed to read back all the registers, which updates the
values on the table.
Register settings can be saved to text file format by selecting “Save Registers” from file menu. Text file
format register settings file can be loaded and programmed automatically by selecting “Load Register”
from file menu.
