恒压驱动
恒压LED驱动电路,是输出电压基本恒定的。常用的恒压驱动电路可分为线性LED恒压驱动电路和开关模式LED恒流驱动电路。线性恒压LED驱动电路比较简单,成本低,适合驱动低功率LED,但电路效率比较低;开关模式恒压LED电路,比较起线性恒压电路效率比较高,可靠性好。由于LED伏安特性的非线性,很小的电压变化就会引起很大的电流变化,如果用恒压源直接驱动,LED电流会随着LED负载电压的微小变化而发生急剧变化,甚至会烧毁LED。因此在实际应用中, 恒压驱动电源一般会在LED负载前接入电阻限流或恒流LED驱动电路。图17所示为基于TDA4863-2G的恒压电路+BCR450线性恒流电路的LED驱动解决方案。
