MAXM17572 uSLIC™ Step-Down Power Module

ADI's Himalaya series of voltage regulator ICs, power modules, and chargers enable cooler, smaller, and simpler power supply solutions. The MAXM17572 is a high-efficiency, synchronous Himalaya step-down DC-DC power module with an integrated controller, MOSFETs, compensation components, and inductor that operates over a wide input-voltage range. The module operates from 4.5 V to 60 V input and delivers up to 1 A output current over a programmable output voltage range of 0.9 V to 12 V. The module significantly reduces design complexity and manufacturing risks and offers a true plug-and-play power supply solution, reducing the time-to-market. The MAXM17572 employs peak-current-mode control architecture.

The MAXM17572 offers programmable switching frequency, RESET output voltage monitoring, adjustable input undervoltage lockout, and programmable soft-start. The module also features hiccup-mode overload protection and a thermal shutdown function.

The MAXM17572 is available in a low-profile, compact, 12-pin 3.5 mm x 3.5 mm x 2.3 mm uSLIC package. Simulation models are available.

The MAXM17572EVKIT# 5 V output evaluation kit (EV kit) provides a proven design to evaluate the MAXM17572 high-voltage, high-efficiency, synchronous step-down DC-DC power module. The EV kit is programmed for 5 V output and delivers load currents up to 1 A. The programmed switching frequency is 900 kHz for optimum efficiency and component size. The EV kit features an adjustable input undervoltage lockout, adjustable soft-start, open-drain RESET signal, and external frequency synchronization. The MAXM17572 module data sheet provides a complete description, features, benefits, and parameters of the part that should be read in conjunction with this EV kit data sheet before operating the EV kit.
