IR21593S Datasheet (International Rectifier)

IR21593S, DIMMING BALLAST CONTROLLER

Packages Description: The IR21592/IR21593 are complete dimming ballast controllers and 600V half-bridge drivers all in one IC.

The architecture includes phase control for transformer-less lamp power sensing and regulation which minimizes changes needed to adapt non-dimming ballasts for dimming.
