2-A to 6-A Integrated Power Solution
1 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).

This user guide provides information on the correct usage of the EVM and an explanation of the numerous
test points on the board.
2 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.
