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
