LMZ36002EVM: 2.5 ~ 7.5V @ 2A, 4.5 ~ 60V in, Buck

Summary

The LMZ36002EVM evaluation module is designed as an easy-to-use platform that facilitates an extensive evaluation of the features and performance of the Simple Switcher® power module. This guide provides information on the correct usage of the EVM and an explanation of the numerous test points on the board.

This EVM features the LMZ36002 synchronous buck power module configured for operation with typical 12-V to 60-V input bus applications. The output voltage can be set to one of five popular values by using a configuration jumper. In similar fashion, the switching frequency can be set to one of five values with a jumper. The full output current rating of the device can be supplied by the EVM. Input and output capacitors are included on the board to accommodate the entire range of input and output voltages.

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 slow-start/tracking, Inhibit/UVLO, PWRGD, and synchronization features of the LMZ36002 device.

The EVM uses a recommended PCB layout that maximizes thermal performance and minimizes output ripple and noise.
