Analog Devices Inc. MAXM17630, MAXM17631, & MAXM17632 Power Modules
Analog Devices Inc. MAXM17630, MAXM17631, and MAXM17632 Himalaya, uSLIC™, Step-Down Power Modules are enabled for cooler, smaller, and simpler power supply solutions. The MAXM17630, MAXM17631, and MAXM17632 are high-efficiency, synchronous step-down DC-DC modules with an integrated controller, MOSFETs, compensation components, and inductor that operate over a wide input-voltage range.
The power 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 devices offer a true plug-and-play power supply solution, significantly reducing design complexity, manufacturing risks, and time to market. Built-in compensation across the output voltage range eliminates the need for external compensation components.
The MAXM1763x power modules feature peak-current-mode control architecture and can be operated in pulse width modulation (PWM), 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%.
The MAXM1763x power modules are available in a low-profile, compact 16-pin, 3mm x 3mm x 1.75mm, uSLIC™ package. Simulation models are also available.
