Maxim Integrated MAX17222 | Demoboard MAX17222EVKIT

Evaluates: MAX17220–MAX17225

Overview

TopologyBoost Converter
Input voltage1.5 V
Output 13 V / 0.1 A

Description

The MAX17222 evaluation kit (EV kit) evaluates theMAX17220–MAX17225 IC family of ultra-low quiescentcurrent step-up DC-DC converters. The MAX17222 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 3k load. Each circuit provides resistorconfigurableoutput voltages from 1.8V to 5V in 100mV/step. Additionally, each circuit output on the EV kit deliversup 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.
