4.5V to 24V, 300mA Himalaya uSLIC Step-Down Power Module

The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power supply solutions. The MAXM17901/MAXM17903 are a family of high-efficiency, synchronous step-down DC-DC modules with integrated controller, MOSFETs, compensation components, and inductor that operate over a wide input-voltage range. The modules operate from 4.5V to 24V input and deliver up to 300mA output current. The MAXM17901 is a fixed 3.3V output modules. The MAXM17903 is an adjustable output (0.9V to 5V) module. The modules significantly reduce design complexity, manufacturing risks, and offer a true plug and play power/supply solution, reducing time-to-market.

Both modules employ peak-current-mode control architecture. To reduce input inrush current, the modules offer a fixed 4.1ms soft-start time.

The MAXM17901/03 modules is available in a low profile, compact 10-pin, 2.6mm × 3mm × 1.5mm, uSLIC™ package.
