EM8609A

EM8609A Transition Mode PFC Controller for LED Lighting General Description EM8609A is a voltage mode PFC controller operating at transition mode. This device provides protections of internal soft start, over voltage protection, over current protection and thermal shutdown. It can minimize the external components counts, and makes the design easy. It also provides functions of low start up current, disable function, under voltage lockout and internal leading edge blanking of the current sensing. This part is available in SOP-8 package.
