Introduction

The TPS84410EVM-001, TPS84210EVM-002, TPS84610EVM-003 Evaluation Module

(TPS84x10EVM-00x) is designed as an easy to use platform that facilitates an extensive evaluation of the

features and performance of the Integrated Power Solution (IPS) devices. The EVM PCB may be

configured with one of three IPS devices (see Table 1).

Description

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 4-A 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.
