Introduction

AI Translation

A high-efficiency synchronous buck constant-current LED driver with a fixed 200KHz switching frequency and output current capability up to 3A. Supports a wide input voltage range of 5V~45V with up to 100% duty cycle output. The integrated loop compensation module effectively reduces system component count, lowers overall power system cost, and minimizes PCB space. The IC features built-in thermal shutdown protection and output current limiting protection.
