Product Details

The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power-supply solutions. The MAXM17900 is a high-efficiency, synchronous, step-down DC-DC power module with integrated controller, MOSFETs, compensation components, and inductor that operates over a wide input voltage range. The module operates from 4V to 24V input voltage and delivers up to 100mA output current over a programmable output voltage from 0.9V to 5.5V. The module significantly reduces design complexity, manufacturing risks and offers a true plug-and-play power supply solution, reducing the time-to-market.

The MAXM17900 employs peak-current-mode control architecture. To reduce input inrush current, the device offers a soft-start feature including a default soft-start time of 5.1ms.

The MAXM17900 is available in a low profile, compact 10-pin 2.6mm x 3mm x 1.5mm uSLIC package.
