Introduction

The LMZ30604EVM-001, LMZ30602EVM-002, LMZ30606 Evaluation Module (LMZ3060xEVM-00x) is

designed as an easy to use platform that facilitates an extensive evaluation of the features and

performance of the Simple Switcher power module. The EVM PCB may be configured with one of three

devices (see Table 1).

Description

The EVM features a LMZ3060x synchronous buck power module 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 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

device. The EVM uses a recommended PCB layout that maximizes thermal performance and minimizes

output ripple and noise.
