Analog Devices / Maxim Integrated Himalaya uSLIC™ MAXM17900 Step-Down Power Modules

Analog Devices Himalaya uSLIC™ MAXM17900 Step-Down DC-DC Power Module integrates a controller, MOSFETs, an inductor, and the compensation components in a compact uSLIC™ package. The device operates from an input voltage of 4.0V to 21V. The MAXM17900 supports an adjustable output voltage from 0.9V to 5.5V and supplies up to 100mA of load current. The high level of integration significantly reduces design complexity and manufacturing risks and offers a true “plug and play” power supply solution, hence reducing the time-to-market.

The Analog Devices MAXM17900 uses peak-current-mode control and operates in pulse-width modulation (PWM) mode. The device is available in a thermally enhanced, compact 10-pin 2.6mm x 3mm x 1.5mm uSLIC package. The MAXM17900 is rated to operate over the full -40°C to +125°C industrial/automotive temperature range.
