PublishTime：2025-03-20

The UCT4171 is a high-efficiency DC-DC Buck/Boost switching regulator designed for LED driver applications. It operates from an input supply of 3.5V to 36V and provides an externally adjustable output current of up to 1.2A. The device operates at a fixed 500KHz switching frequency, making it easy to choose external inductors. It supports dimming via DC voltage or PWM signal from 100Hz to 20KHz. The UCT4171 offers various protections like Soft-Start, Under-voltage Lockout, Current Limiting, Over-Voltage Protection, and Thermal Regulation and Shutdown. It is available in the SOT89-5 package and is suitable for LED lighting applications.
