IR21591 - (IR2159 / IR21591) DIMMING BALLAST CONTROL IC

Download the IR21591 datasheet PDF. This datasheet also covers the IR2159 variant, as both devices belong to the same (ir2159 / ir21591) dimming ballast control ic family and are provided as variant models within a single manufacturer datasheet.

Description

Description: The IR2159/IR21591 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.
