ML4830- Electronic Ballast Controller
GENERAL DESCRIPTION
The ML4830 is a plete solution for a dimmable, high power factor, high efficiency electronic ballast. Contained in the ML4830 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 ML4830 to increase system noise immunity by using a high amplitude oscillator, and a gain modulator. An overvoltage protection parator...
