EM8822A Single stage Buck/Buck-Boost PFC Controller for LED Lighting Applications General Description EM8822A is a voltage mode Buck/Buck-boost PFC controller operating at transition mode. It keeps the Buck / Buck-boost converter in constant on time operation to achieve high power factor. 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. This part is available in SOP-23-6 package.
