SSL2103T/1
NXP SSL2103T/1 发光二极管驱动器, 1输出, 降压, 反激, 12V-28V输入, 100kHz开关, 12V输出, SOIC-14
The is a Switched Mode Power Supply SMPS Controller IC that operates in combination with a phase cut dimmer directly from the rectified mains. It is designed to drive LED devices. The device includes a circuit to allow direct start-up from the rectified mains voltage. It gives the application designer flexibility to - use an external power switch to allow the IC to provide any power and to use an external bleeder transistors to provide extended dimmer interoperability.
