TDA4863-2G中文资料功率控制芯片数据手册Infineon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)
