The VIPer22A is low cost monolithic smart power devices with integrated PWM controller designed to operate in the wide range input voltage, from 90 to 264Vac.
The VIPer22A internal control circuit offers benefit such as: automatic burst mode in low load condition, overvoltage protection in hiccup mode, and large voltage range on the VDD pin.
This isolated VIPer22A constant current LED driver has been configured to drive 2 to 8 LEDs.
