TDA4863-2G数据手册Infineon中文资料规格书

描述 Description

Fully compatible with the world standard, TDA4863-2G 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.

特性 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 TDA48632G 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)
