Description
The MAX17225 evaluation kit (EV kit) evaluates theMAX17220–MAX17225 IC family of ultra-low quiescent current step-up DC-DC converters. The MAX17225 EVkit 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 3kΩ load. Each circuit provides resistor-configurable output voltages from 1.8V to 5V in 100mV/step.
