The Himalaya series of voltage regulator ICs and power modules enable cooler, smaller, and simpler power supply solutions. The MAXM17630/MAXM17631/MAXM17632 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 36V and deliver up to 1A output current. The MAXM17630 and MAXM17631 are fixed 3.3V and 5V output modules, respectively. The MAXM17632 is an adjustable output (0.9V to 12V) module. The modules significantly reduce design complexity, manufacturing risks, and offer a true plug-and-play power-supply solution, reducing time-to-market. Built-in compensation across the output-voltage range eliminates the need for external compensation components.These modules feature peak-current-mode control architecture. The modules can be operated in pulse-width modulation (PWM), or pulse-frequency modulation (PFM), or discontinuous-conduction mode (DCM) to enable high efficiency under light-load conditions.The feedback-voltage regulation accuracy over -40°C to +125°C for the module family is ±1.2%. These power modules are available in a low profile, compact 16-pin, 3mm x 3mm x 1.75mm, uSLIC™ package.
