1 Introduction
The TPS23525 EVM provides a jump-start to anyone designing a redundant feed –48-V system. The EVM
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.
Additionally, the EVM includes circuitry that supports auxiliary bulk capacitors. This “auxiliary bulk
capacitor” approach is useful when designing for large hold-up times (example: 10 ms) making the hot-
swap design more manageable by reducing the initial charge on the capacitor.
1.1 Features
This EVM has the following features:
• Inrush current control
• Hot-swap output short-circuit protection
• Reverse current protection
• Dual supply ORing
• Reverse hookup protection

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 the hot swap is up
• Set the input power-supply voltage to the desired operating input voltage
• Turn the power supply off
• Jump pins 1-2 on J5
• Leave pins 1-2 on J6 open
• Connect the positive voltage lead from the power-supply A to J1 (RTN). Connect the ground lead from
the power-supply A to J10 (Neg48V_A).
• Connect the positive voltage lead from the power-supply B to J3 (RTN). Connect the ground lead from
the power-supply B to J7 (Neg48V_B).
• Make sure all voltmeter or oscilloscope GNDs are tied to VEE
• 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 scope GND is tied to RTN and a probe is placed on TMR, that creates approximately 5 μA of pullup
current which can overpower the pull down of the TMR pin and result in an undesired time out.
