PT5631
Dimming Ballast Controller IC
DESCRIPTION
PT5631 is a dimming ballast controller, which is
available to implement closed loop feedback control of
the lamp power. PT5631 has external programmable
features, such as preheat time and preheat current. All
of these provide a great degree of flexibility for the
ballast design engineers. With different connections,
PT5631 has the dimming ability with TRIAC,
potentiometer or remote controller. And the PT5631 is
available in both 16-pin DIP and 16-pin SOP
packages.
