Overview
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.
Applications General LED lighting applications Bulb lamp Tube lamp PAR lamp Pin Configuration Ordering Information Part Number Package EM8822AJ SOP-23-6 Remark EM8822A Features Single stage Buck/Buck-Boost PFC controller Voltage Mode Control Valley turn on of the MOSFET to achieve lower switching loss Low Start Up Current : 6uA typical Maximum gate drive voltage at 19.
5V Over Voltage Protection for IC bias voltage LED Open/Short Protection Internal ove...
