LMZ31710EVM-001: 0.6 ~ 5.5V @ 10A, 2.95 ~ 17V in
Summary
The LMZ31710EVM-001, LMZ31707EVM-002 and LMZ31704EVM-003 evaluation modules are 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 LMZ31710 (10-A), LMZ31707 (7-A), or LMZ31704 (4-A), synchronous buck power module configured for operation with typical 5-V and 12-V input bus applications. The output voltage can be set to one of seven popular values by using a configuration jumper. In similar fashion, the switching frequency can be set to one of seven 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 PWRGD, Inhibit/UVLO, synchronization, and slow-start/tracking features of the LMZ317xx device. The EVM uses a recommended PCB layout that maximizes thermal performance and minimizes output ripple and noise.
