MAX17222EVKIT#: 3V @ 100mA, 0.4 ~ 5.5 Vin, Boost

Summary

The MAX17222 evaluation kit (EV kit) evaluates the MAX17220–MAX17225 IC family of ultra-low quiescent current step-up DC-DC converters. The MAX17222 EV kit features two independent circuits to evaluate two different IC packages of the MAX17220–MAX17225 family. Both circuits on the EV kit operate over an input range of 400mV to 5.5V, depending on load, with 0.88V typical startup with 3k load.

Each circuit provides resistor configurable output voltages from 1.8V to 5V in 100mV/step. Additionally, each circuit output on the EV kit delivers up to 100mA, 225mA, or 425mA of current, depending onthe input voltage to the output voltage ratio.

The EV kit comes with the MAX17222ELT+ installed, while the MAX17225ENT+ is a future product.
