User's Guide SLUU394 – November 2009 Using the TPS2560EVM-424 and TPS2561EVM-424 This user’s guide describes the TPS2560EVM-424 and TPS2561EVM-424 evaluation modules (EVM). This guide contains the EVM schematic, list of materials, assembly drawing, and top and bottom board layouts. 1 Introduction The TPS2506EVM-424 and TPS2561EVM-424 are evaluation modules (EVM) for Texas Instruments’ power-distribution switches with adjustable current-limit. These EVMs operate over a 2.5-V to 6.5-V range.

Getting Started www.ti.com 4 Getting Started Preset the power supply to 5 V and turn off. Connect the power supply output to the input terminals of the HPA424. Remove jumper J2. Slide S1 and S2 to disable the TPS2556 or TPS2557. Turn on the power supply to apply 5.0 V to the EVM input-power terminals. VOUT1 should be 0 V. Slide S2 to enable the device. For TPS2556, set S1 to LO; for TPS2557, set S1 to HI. VOUT1 should be VIN + / - 0.3 V.
