Overview

The MAX17552AUB+ is a high-efficiency, ultra-small, synchronous step-down DC-DC converter with integrated MOSFETs that operates over a wide 4V to 60V input voltage range. It delivers up to 100mA of output current with an adjustable output voltage from 0.8V to 0.9 x VIN, making it ideal for high-voltage industrial and distributed supply applications.

Why Choose This Part

This regulator features a low 22uA quiescent current and 1.2uA shutdown current to maximize battery life in standby modes. It eliminates the need for an external Schottky diode through synchronous operation and supports a wide switching frequency range from 100kHz to 2.2MHz to optimize for size or efficiency.

Applications

Industrial Sensor Power
Converts high-voltage industrial rails directly to low-voltage sensor supplies with high efficiency.
4-20mA Loop-Powered Systems
Provides efficient power conversion for low-current control loops requiring wide input voltage tolerance.
HVAC and Building Automation
Reliable regulation for climate control systems and automated building management hardware.
Battery-Powered High-Voltage Equipment
Minimizes standby power consumption in battery-backed systems using its 1.2uA shutdown current.
