PT5611
Dimming Ballast Controller IC
DESCRIPTION
PT5611 is a dimming ballast controller, which is
available to implement closed loop feedback control of
the lamp power. PT5611 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,
PT5611 has the dimming ability with potentiometer or
remote controller. And the PT5611 is available in both
16-pin DIP and 16-pin SOP package.
