This user’s guide describes the characteristics, operation, and use of TI's evaluation module (EVM) for the TPS6287x-Q1 devices. The TPS62876EVM-198 is designed to help the user easily evaluate and test the operation and functionality of the TPS62876-Q1 buck converters. The TPS62876EVM-198 can be used to evaluate the TPS62874-Q1, TPS62875-Q1, TPS62876-Q1, and TPS62877-Q1. The EVM converts 2.7-V to 6.0-V input voltage to a regulated 0.75-V output voltage. The output current can go up to 25-A for the TPS62876EVM-198. 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 TPS62876-Q1 device is a high-frequency, synchronous step-down converter optimized for a small solution size and high efficiency. The device focuses 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 4.05-mm × 3.05-mm, 24-pin VQFN package.
