1Overview
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
• Pb-free lead plating ; RoHS compliant
1.2
Improvements Referred to TDA 4862 and TDA 4863
• 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)
