MAX77231EVKIT# : 11.2V @ 10mA, 2.7 ~ 4.8V in, Boost

Summary

The MAX77231 evaluation kit (EV kit) is a fully assembled and tested PCB for evaluating the MAX77231 low-noise step-up DC-DC converter. It is optimized for boost applications requiring very low ripple/noise and small PCB space.

The EV kit is set up to provide an 11.2V output from an input voltage ranging from 2.7V to 4.8V, and can deliver up to 10mA of current. The output ripple and noise are suppressed to 35μVRMS. Other output voltages up to 16.2V can be factory set. Jumpers are provided to help evaluate features of the MAX77231 IC.
