SFL530 是一个低成本、高恒流精度、原边反馈PSR (Primary Side Regulation) 控制的隔离式AC/DC LED恒流功率开关，适用于LED照明领域。在全电压范围内实现高精度的恒流输出，恒流精度在+/-5%以内。
SFL530 采用专利的"NC-Aux/PSRTM "控制技术，可以省去供电辅助绕组，同时集成了功率MOSFET，大大降低了系统成本。
SFL530内置高压启动技术，可以实现小于100ms的开机启动，实现了LED灯的"即开即亮"功能；集成了专利的恒流控制算法，从而大大提高LED输出电流的精度和一致性。
SFL530集成了诸多保护功能，包括VDD欠压保护(UVLO，Under Voltage Lockout)，VDD 过压钳位保护，LED短路/开路保护，逐周期电流限制，管脚浮空保护等等。
SF530提供TO-92封装形式。</p>
