TDA4863G
Overview
Fully compatible with the world standard, TDA4863G is optimized to offer extremely compact and cost effective PFC solutions for electronic ballast and off-line SMPS. By using a zero current detector for discontinuous operation mode a near unity power factor and an excellent THD are achieved.
Summary of Features
- High power factor Power
- Controls boost converter as active harmonic filter for low THD
- Start up with low current consumption
- Zero current detector for discontinuous conduction mode
- Output overvoltage protection
- Output undervoltage lockout
- Internal start up timer
- Totem pole output with active shut down
