基于Boost的大功率LED恒流驱动电路
High Power LED Driver Circuit with Constant Current Based on Boost
摘要
Abstract
Considering the problem of how to improve the reliability of LED driver circuit ,this paper introduces a High Power LED Driver Circuit with Constant Current based on Boost, and analyses the working principle as well as the performance features of this circuit. This circuit uses boost way and I/V switching circuit, which supplies constant current drive ability and wires multiple LEDs. In addition,the boost way uses LM2577 as the core .It makes the LED current work in a steady state in a long time and has high reliability meanwhile. All aforementioned have been verified through experiments.
