基于Boost拓扑的侧导光LED背光源电容平衡式驱动电路设计

The Design of Capacitor Balanced Driver for Edge-lit LED Backlight Based on Boost Topology

以Boost拓扑电路为基础,运用电容平衡的方式设计实现了一路Boost升压电路驱动两串LED灯条,同时恒流工作的LED背光源驱动电路。

Based on boost topology, this paper introduces a LED driver circuit that uses a capacitor to achieve one boost circuit drive two strings of LED light string work in a constant current mode.
