Introduction

1 Introduction

The TPS20xxEVM-293 and TPS20xxEVM-296 are evaluation modules (EVM) for the Texas Instruments family of two-channel, current-limited, power-distribution switches. These EVMs operate over a 2.7-V to
5.5-V range and provide a continuous output current of up to 1.5 A (see Table 1 and Table 2). 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 TPS20xxEVM-293 accepts an S0-8 packaged power-distribution switch whereas the TPS20xxEVM-
296 accepts MSOP-8 packaged switch with a thermal pad. These switches have an enable input, an overcurrent status output, and overtemperature shutdown; the switch pinouts are identical.
Table 1 and Table 2 summarize the available EVM options.
