Description

The MAX38647B WLP evaluation kit (EV kit) evaluates the MAX38647B IC in a wafer-level package (WLP). The MAX38647B is a tiny, 1.8V to 5.5V Input, 440nA IQ, 175mA nanoPower buck converter with four-level VSEL. The EV kit operates from an input range of 1.8V to 5.5V and provides resistor-configurable output voltages from 0.5V to 1.8V. The MAX38647B can change voltage dynamically using two voltage-select (VSEL) pins. The EV kit delivers up to 175mA of output current. The EV kit comes with the MAX38647BANA+ installed. For full MAX38647B IC features, benefits, and parameters, refer to the MAX38647B data sheet.
