DESCRIPTION

The PT5621 is an electronic ballast controller IC

specifically for three-way dimming fluorescent lamps.

The features of the controller include negative-feedback

closed-loop control of the lamp current, programmable

preheat time, low start-up current and precise oscillating

frequency. PT5621 is available in both DIP16 and

SOP16 packages.
