Overview
August 1997 Application Brief 42022 ML4833 220V Non-Dimming Ballast Design GENERAL DESCRIPTION This Application Brief exists as a supplement to Application Note 63.
When used with Application Note 63, this document contains all the necessary information to convert an ML4833 Evaluation Board into a low-cost, non-dimming 220V ballast.
This power factor corrected, 60W non-dimming ballast operates over a 187 to 253VRMS line, and is designed to power two series connected F32T8 lamps.
The design preserves the features of the dimming ballast, which include: • • • • • • 0.
99 minimum power factor Less than 10% THD Programmable starting sequence for low glow current and extended lamp life Greater tha...
