TPS84250EVM-001: 2.5 ~ 15V @ 2.5A, 7 ~ 50V in

The TPS84250EVM-001 evaluation module is designed as an easy-to-use platform for evaluating the features and performance of the Integrated Power Solution (IPS) device. The user's guide provides information on the correct usage of the TPS84250EVM-001 and an explanation of the numerous test points on the board.

The TPS84250EVM-001 evaluation module features a TPS84250 device configured for operation from a 7V to 50V input supply. The output voltage can be set to one-of-five popular values by using a simple configuration jumper. Similarly, the switching frequency can be set to one-of-four values by use of a jumper. The full, 2.5A-rated output current can be supplied by the EVM. A minimal amount of input and output capacitance is used on the board. Component pads are provided for additional input and output capacitors if desired.

A simple 5V pull-up supply for the PWRGD pin is provided on the EVM. It is powered from the input voltage supply. Test points are provided that allow measurement of efficiency, power dissipation, input ripple, output ripple, line and load regulation, soft-start behavior, transient response, and undervoltage lockout (UVLO) behavior. The EVM uses a recommended printed-circuit board (PCB) layout that maximizes thermal performance and minimizes output ripple and noise.
