Texas Instruments has launched the TPS23525EVM-815 module that contains evaluation and reference circuitry for the TPS23525. The TPS23525 is a hot swap voltage controller IC targeted at telecom applications. The module includes input clamping to support lightning surge (up to 2kV), various FET placeholders to support various power levels and an output inductor to mimic any electro-magnetic interference (EMI) filter.
The module also includes the circuitry that supports auxiliary bulk capacitors. This approach is useful when designing for large hold-up times (e.g. 10ms) making the hot-swap design more manageable by reducing the initial charge on the capacitor.
