Overview

July 2000 PRELIMINARY ML4832* Electronic Dimming Ballast Controller 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.
This system produces a power factor of better than 0.
99 with low input current THD at > 95% efficiency.
Special care has been taken in the design of the ML4832 to increase system noise immunity by using a high amplitude oscillator, and a current-fed multiplier.
