ML4831* Electronic Ballast Controller
GENERAL DESCRIPTION
The ML4831 is a complete solution for a dimmable, high power factor, high efficiency electronic ballast.
Contained in the ML4831 are 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 over-voltage protection.
This system produces power factors of better than 0.
99 with low input current THD at 95% efficiency.
Special care has been taken in the design of the ML4831 to increase system noise immunity by using a high amplitude oscillator, and a current fed multiplier.
An over-voltage protection compara...
