基于DC-DC的白光LED驱动电路的研究与设计
Research and Design of White LED Driver Based on DC/DC
【摘要】 LED由于环保、寿命长、低耗电量等特性,近年来在各行业得以快速应用及发展,LED驱动电路的研究与设计也成了关注热点。通过设计升压式DC-DC转换芯片,采用PWM控制方式和电流控制模式,对外接串联的LED进行驱动。然后用Spectre软件完成了总体电路的模拟和仿真,通过对其结果分析,表明系统能够稳定工作,并且达到设计指标要求。
【Abstract】 LED has developed rapidly in recent years because of its characteristic, such as environmental, durable and low power consumption etc. The research and the design of LED drives also become popular. This paper designs the boost DC/DC circuits with PWM dimming and current-mode control to drive the load LEDs. Then it simulated with the Spectre software and the results show that this system can work properly and can also meet the design requirements.
