LMZM33602EVM: 2.5V, 3.3V, 5V, or 12V @ 2A, 4 ~ 36V in

Summary

This EVM features the LMZM33602 synchronous buck power module configured for operation with typical 4-V to 36-V input bus applications. The output voltage can be set to one of four popular values by using a configuration jumper. Similarly, the switching frequency can be set to one of four 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 and component footprints are provided for use of the EN, UVLO, PGOOD, and SYNC features of the LMZM33602 device. The EVM uses a recommended PCB layout that maximizes thermal performance and minimizes output ripple and noise.

Meets EN55011 Class B Radiated EMI Standards
