TPS2500/1, Power-Distribution Switch
With Low Voltage Input EVM
This user’s guide describes the TPS2500/1DRCEVM evaluation modules (EVM). This guide contains the
EVM schematic, bill of materials, assembly drawing, and top and bottom board layouts.
The TPS2500/1DRCEVM is an evaluation module (EVM) for Texas Instruments’ family of
power-distribution switches with adjustable current-limit. These EVMs operate over a 1.8-V to 5.25-V
range providing 5-V output for USB devices. An onboard jumper sets the output current-limit to either 0.5
A or 1 A. Test points provide convenient access to all critical node voltages.
The silkscreen outline on the PCB top-side encloses components found in a typical USB application.
The TPS2500/1 is in an SON package with a thermal pad. These switches have an enable input, an
overcurrent status output, and overtemperature shutdown.

The EVM has been tested to IEC 61000-4-2. The level used was 8-kV contact discharge and 15-kV air
discharge. Surges were applied to the EVM input and output. No damage to the TPS2500/1 was
observed.
