TPS20xxEVM-295 Bill of Materials
The TPS20xxEVM-295 family of evaluation modules (EVM) support the four-channel, current-limited,
power-distribution switches in

. These EVMs operate over a 2.7-V to 5.5-V range and provide a
continuous output current of up to 0.5 A. Test points provide convenient access to all critical node
voltages.
