Introduction
The TPS2559EVM-624 evaluation module (EVM) is a fully assembled and tested circuit for evaluating the
TPS2559 precision-adjustable current-limited power distribution switch. The EVM contains header
connectors for easy connection to the external test and application circuitry.

Description
The PCB top-side accepts a power-distribution switch in a VSON-10 (DRC) package with a thermal pad.
These switches have an enable input, an overcurrent status output, and overtemperature shutdown.
TPS2559EVM-624 is enabled active high.
