This user’s guide describes the characteristics, operation, and use of TI's evaluation module (EVM) for the TPS62873-Q1 devices. The TPS62873EVM-144 is designed to help the user easily evaluate and test the operation and functionality of a stacked configuration of two TPS62873 buck converters. The device also can be used to evaluate TPS62870-Q1, TPS62871-Q1, and TPS62872-Q1 devices in this configuration. The EVM converts a 2.7-V to 6.0-V input voltage to a regulated 0.75-V output voltage. The output current of this EVM can go up to 30 A. This user’s guide includes setup instructions for the hardware, a printed-circuit board (PCB) layout, a schematic diagram, and a bill of materials (BOM).
