TPS84410EVM-001: 0.8V, 1.2V, 1.8V, 2.5V, 3.3V @ 4A

Summary

The EVM features a TPS84x10 synchronous buck IPS device configured for operation with typical 3.3-V and 5-V input bus applications. The output voltage can be set to one of five popular values by using a simple configuration jumper. In similar fashion, the switching frequency can be set to one of four values by use of a jumper.

The full 2A, 4A, or 6A 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. Monitoring test points are provided to allow measurement of efficiency, power dissipation, input ripple, output ripple, line and load regulation, and transient response. Control test points are provided for use of the PWRGD, Inhibit/UVLO, synchronization, and slow-start/tracking features of the IPS device. The EVM uses a recommended PCB layout that maximizes thermal performance and minimizes output ripple and noise.
