Description

The Himalaya series of voltage-regulator ICs and power modules enable cooler, smaller, and simpler power-supply solutions. The MAXM17710-MAXM17726 family of dual output regulators integrate a high efficiency 150mA synchronous step-down DC-DC converter and a high power supply rejection ratio (PSRR), low noise, 50mA linear regulator into uSLIC™ power modules. The modules operate from a wide input voltage range of 4V to 60V. The step-down converter and linear regulator can deliver output currents up to 150mA and 50mA, respectively. MAXM17710–MAXM17714 modules offer fixed 3.3V output from the DC-DC converter. MAXM17715–MAXM17720 modules offer fixed 5V output from the DC-DC converter. MAXM17721–MAXM17726 modules offer adjustable output voltage from the DC-DC converter. The output of the DC-DC converter serves as the input to the linear regulator. The linear regulators offer fixed output voltages between 1.2V and 3.3V in different modules. Refer to the Ordering Information for a complete list of part numbers. The modules significantly reduce design complexity, manufacturing risks, and offer a true plug-and-play power supply solution, reducing time to market.

The modules employ peak current mode control architecture for step-down converters. To reduce input inrush current, the modules offer a fixed soft-start of 5.1ms (typ) for the step-down converter and 1.1ms (typ) for the linear regulator.

The modules are available in a low profile, compact 10-pin (2.6mm x 3mm x 1.5mm) uSLIC package.
