Description

General part information

MAX17571 Series

The Himalaya series of voltage regulator ICs, power modules, and chargers enable cooler, smaller, and simpler power supply solutions. The MAX17571, a highefficiency, high-voltage, Himalaya synchronous stepdown DC-DC converter with integrated MOSFETs operates over an input voltage range of 4V to 60V. The converter can deliver up to 1.5A current. Output voltage is programmable from 0.9V up to 90% of VIN. The feedback voltage regulation accuracy over -40°C to +125°C is ±1.2%. Built-in compensation across the output voltage range eliminates the need for external compensation components.The MAX17571 features peak-current-mode control architecture and operates in fixed frequency forced pulse-width modulation (PWM) mode. A programmable soft-start feature allows users to reduce input inrush current. The device also incorporates an enable/input undervoltage lockout pin (EN/UVLO) that allows the user to turn on the part at the desired input voltage level. The MAX17571 offers a low minimum on time that allows high switching frequencies and a smaller solution size.The MAX17571 is available in a 12-pin (3mm x 3mm) TDFN-EP package. Simulation models are available.
