MAXM15462EVKIT

Description

Create a design and simulate using EE-Sim^® tools:

The MAXM15462 3.3V output evaluation kit (EV kit) provides a proven design to evaluate the MAXM15462 high-voltage, high-efficiency, synchronous step-down DC-DC module. The EV kit is programmed to deliver 3.3V output for loads up to 300mA. The EV kit features an adjustable input undervoltage lockout, selectable mode, and open-drain active-low RESET signal. The MAXM15462 data sheet provides a complete description of the module that should be read in conjunction with this EV kit data sheet prior to modifying the demo circuit. For full module features, benefits and parameters, refer to the MAXM15462 data sheet.
