Description
The MAX17220 evaluation kit (EV kit) evaluates theMAX17220–MAX17225 IC family of ultra-low quiescentcurrent step-up DC-DC converters. The MAX17220 EVkit features two independent circuits to evaluate twodifferent IC packages of the MAX17220–MAX17225family. Both circuits on the EV kit operate over an inputrange of 400mV to 5.5V, depending on load, with 0.88Vtypical startup with 3kΩ load. Each circuit providesresistor-configurable output voltages from 1.8V to 5V in100mV/step.The EV kit comes with the MAX17220ELT+ andMAX17220ENT+ installed.
