Description

The Himalaya series of voltage regulator ICs, power modules, and chargers enable cooler, smaller, and simpler power supply solutions. The MAX17783C is a high-efficiency, high-voltage, Himalaya step-down DC-DC converter with an integrated high-side MOSFET operating over a wide input-voltage range of 6V to 60V. It can deliver up to 2.5A current, and generate output voltages from 0.9V up to 90% of VIN. The device features internal compensation.

The MAX17783C device uses peak current-mode control architecture. The device operates in Low Iq mode at light loads to enable high efficiency. The MAX17783C offers a low minimum on-time that allows high switching frequencies and smaller solution sizes.

The feedback-voltage regulation accuracy is ±1.6% over -40°C to +125°C. The MAX17783C is available in a compact 10-pin (3mm x 3mm) TDFN package. Simulation models are available.
