4.5V to 60V, 300mA Step-Down uSLIC Power Module

The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power-supply solutions. The MAXM15065/MAXM15066/MAXM15067 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 60V input and deliver up to 300mA output current. The MAXM15065 and MAXM15066 are fixed 3.3V and 5V output modules respectively. The MAXM15067 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 MAXM15065/MAXM15066/MAXM15067 modules employ peak-current-mode control architecture. To reduce input inrush current, the modules offer a fixed 3.75ms soft-start time.

The MAXM15065/MAXM15066/MAXM15067 modules are available in a low profile, compact 10-pin, 2.6mm x 3mm x 1.5mm, µSLIC ™ package.
