1 Introduction
The TPS23523 EVM is meant to give a jump start to anyone designing a –48-V system with a single
supply that needs to support supply dips and other transients. It includes input clamping to support
lightning surge (up to 2 kV), various FET placeholders to support various power levels, and an output
inductor to mimic any EMI filter before the DC/DC converter. The EVM can be configured in two ways (via
jumpers) to evaluate 2 common architectures seen in the –48-V telecommunication space.
Figure 1 shows a block diagram for the first configuration of the EVM. The TPS23523 provides inrush
control, short circuit protection, reverse current protection, and reverse hookup protection. The INA226
provides current, voltage, and power monitoring. If the downstream DC/DC is isolated and powers the
microcontroller, an isolator is required to communicate between the microcontroller and the INA226. Thus,
the ISO1541 is added to provide this functionality. Also note that the TPS23523 helps to create a bias rail
to power both the INA226 and ISO1541. For detailed operation of the INA226, consult INA226EVM

Figure 1. TPS23523-863 Typical Configuration
As Figure 2 shows, the TPS23523 EVM can also be configured to implement a more sophisticated
architecture. In this architecture there is a common 48-V input that is used to power both the load on the
board and the mid plane. The ORing and current monitoring is performed on the 48-V input. Then the hot-
swap function is performed on just the load present on the board. The remaining current powers the mid
plane, which has its own plug-in cards with hot swap on them.

3.2 Equipment Setup
Use the following equipment list and setup steps to work with the EVM:
• 2× power supplies capable of ≥60 V and ≥15 A (preferred)
• Resistive or electronic load, only turn on the load after hot swap is up
Follow these steps to properly set-up the device:
1. Set the input power-supply voltage to the desired operating input voltage.
2. Turn the power supply off.
3. Jump pins on J7 and J8, depending on the desired resistor.
4. Leave pins 1-2 on J3 open.
5. Connect the positive voltage lead from the power supply to J1 (RTN). Connect the ground lead from
the power supply to J4 (Neg48V).
6. Make sure all voltmeter and oscilloscope GNDs are tied to VEE.
7. Turn the power supplies on.
3.3 Scope Considerations
Observe the following scope considerations:
• Most scopes have a 10-MΩresistance between scope GND and probe. If a scope GND is tied to RTN,
and a probe is placed on TMR that is approximately 5 µA of pullup current, this can overpower the
pulldown of the TMR pin and result in a time out.
• Scope GND is tied to Earth GND, which has some capacitance to supply (+) and (–) terminals. This
may cause system noise.

The INA226 measures the voltage on the VBUS pin, which is tied to VIN through a resistor divider. Figure 46
illustrates a simplified diagram. Note that there is an 830-kΩresistor that must be accounted for. For this
EVM, R1= 100 kΩand R2= 5.49 kΩ. To compute VIN, MEAS from VBUS, MEAS measured, first compute RBOT
and then compute the resistor divider ration as follows:
(1)
(2)
Figure 46. Effective Circuit for Voltage Monitoring
Table 6 shows the current monitoring accuracy results. The VSNS was measured between TP19 and
TP7, which is before the RC filter going into the IC. The results show that the sense resistor is responsible
for the majority of the error and roughly equals 2%. Note that on this PCB, a simple two-terminal, 2-mΩ
resistor was used. If greater accuracy is desired, 4-terminal resistors or higher-accuracy resistors can be
used. Note that the IC + Other Error sources are 0.5% at 1 A and down to 0.1% at 10 A.

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.

Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to
correct the interference at his own expense.

FCC Interference Statement for Class B EVM devices
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more
of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
•Consult the dealer or an experienced radio/TV technician for help.
