Analog Devices / Maxim Integrated MAXM17572 Himalaya uSLIC Step-Down Power Module

Analog Devices Inc. MAXM17572 Himalaya uSLIC Step-Down Power Module is a high-efficiency, synchronous Himalaya step-down DC-DC power module. The power module features an integrated controller, MOSFETs, compensation components, and an inductor (works over a wide input voltage range). The low-profile, compact, 12-pin 3.5mm2 x 2.3mm uSLIC packaged module operates from 4.5V to 60V input and delivers up to 1A output current over a 0.9V to 12V programmable output voltage range.

The MAXM17572 employs a peak-current-mode control architecture and offers a programmable switching frequency, RESET output voltage monitoring, adjustable input undervoltage lockout, and a programmable softstart. The module also features hiccup-mode overload protection and a thermal shutdown function. ADI MAXM17572 significantly reduces design complexity and manufacturing risks while offering a true “plug-and-play” power supply solution, reducing the time-to-market.
