ML4832 Datasheet Electronic Dimming Ballast Controller

Manufacturer: Micro Linear

Overview: July 2000 PRELIMINARY ML4832* Electronic Dimming Ballast Controller GENERAL.

General Description

The ML4832 is a complete solution for a dimmable/nondimmable, high power factor, high efficiency electronic ballast.

The BiCMOS ML4832 contains controllers for “boost” type power factor correction as well as for a dimming ballast.

The power factor circuit uses the average current sensing method with a gain modulator and overvoltage protection.

Key Features

  • s s s s s s s s s s Complete power factor correction and dimming ballast control in one IC Low distortion, high efficiency continuous boost, average current sensing PFC section Programmable start scenario for rapid or instant start lamps Lamp current feedback for dimming control Variable frequency dimming and starting Programmable restart for lamp out condition to reduce ballast heating Over-temperature shutdown replaces external heat sensor for safety PFC overvoltage comparator eliminates outp.
