Description

The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power-supply solutions. The MAXM17904/MAXM17905/MAXM17906 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 MAXM17904 and MAXM17905 are fixed 3.3V and 5V output modules respectively. The MAXM17906 is an adjustable output (0.9V to 6.3V) module. The modules significantly reduce design complexity, manufacturing risks, and offer a true plug and play power/supply solution, reducing time-to-market.

The MAXM17904/MAXM17905/MAXM17906 modules employ peak-current-mode control architecture. To reduce input inrush current, the modules offer a fixed 3.75ms soft-start time.

The MAXM17904/MAXM17905/MAXM17906 modules are available in a low profile, compact 10-pin, 2.6mm x 3mm x 1.5mm, µSLIC™ package.
