【产品】高精度原边反馈LED恒流控制芯片HE3361，可实现很高的功率因数及很低的总谐波失真
概述
LED隔离芯片HE3361是一款单级、带有源功率因数校正的高精度原边反馈LED恒流控制芯片，适用于85Vac~265Vac全范围输入电压的反激式隔离或升降压型非隔离LED恒流电源。
HE3361集成有源功率因数校正电路，可以实现很高的功率因数和很低的总谐波失真。由于工作在电感电流临界连续模式，功率MOS管处于零电流开通状态，开关损耗得以减小，同时变压器的利用率也较高。
HE3361工作于原边反馈模式，无需次级反馈电路，即可实现高精度输出恒流控制，节约了系统成本和体积，提高了系统的可靠性。
HE3361内置了线电压和负载补偿模块，可以达到优异的线电压调整率和负载调整率。线电压补偿系数还可以通过外部元件灵活调整。HE3361内置多重保护功能来加强系统可靠性，包括LED开路保护、LED短路保护、芯片供电过压保护、欠压保护、电流采样电阻开路保护和逐周期限流等。所有的保护都具有自动重启功能。另外，HE3361具有过热调节功能，在驱动电源过热时减小输出电流，以提高系统的可靠性。
