Overview
1.1 Features
IC for sinusoidal line-current consumption
Power factor achieves nearly 1
Controls boost converter as active harmonic
filter for low THD
Start up with low current consumption
Zero current detector for discontinuous
operation mode
Output overvoltage protection
Output undervoltage lockout
Internal start up timer
Totem pole output with active shut down
Internal leading edge blanking LEB
1.2 Improvements Compared to TDA 4862 and
TDA4863
Suitable for universal input applications with low THD at low load conditions
Very low start up current
Accurate OVR and V
ISENSEmax threshold
Competition compatible V
CC thresholds
Enable threshold referred to V
VSENSE
Compared to TDA4863 a bigger MOS Transistor can be driven (see 2.10)
