Infineon Technologies AG AC-DC PWM-PFC Controller, PFC-DCM (discontinuous conduction mode) ICs TDA4863-2

Fully compatible with the world standard, TDA4863-2 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
- Internal leading edge blanking LEB
- Improvements of TDA48632 to TDA4862:
- Very low start up current
- Very low comparator and multiplier offsets for universal input applications
- High sophisticated amplifier for low distortion inteferences caused by MOSFET switching
- Accurate overvoltage threshold
- High gate drive capability (TDA48632 only)
Target Applications:
- SwitchedMode Power Supplies
- Electronic Ballasts
