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).

The TPS62873 device is a high-frequency, synchronous step-down converter optimized for a small solution size and high efficiency. The devices focus on high-efficiency, step-down conversion over a wide output current range. At medium to heavy loads, the converter operates in PWM mode and automatically enters power save mode operation at light load to maintain high efficiency over the entire load-current range. The device is available in a 2.55-mm × 3.55-mm, 16-pin VQFN package.
