The Himalaya series of voltage regulator ICs, power modules, and chargers enables cooler, smaller, and simpler power supply solutions. The MAX17662 is a high-efficiency, Himalaya synchronous step-down DC-DC converter with integrated MOSFETs operating over an input-voltage range of 3.5V to 36V. It can deliver up to 2A current. Output voltage is programmable from 0.6V up to 90% of V_IN. Built-in compensation across the output-voltage range eliminates the need for external compensation components.

The MAX17662 features a peak-current-mode control architecture. The MAX17662 can be operated in forced pulse-width modulation (PWM), or discontinuous-conduction mode (DCM) to enable high efficiency under full-load and light-load conditions. The MAX17662 offers a low minimum on-time that allows high switching frequencies and a smaller solution size.

The feedback-voltage regulation accuracy over -40°C to +125°C is ±1.33%. The device is available in a 16-pin (3mm x 3mm) TQFN-EP package. Simulation models are available.
