描述 Description

Fully compatible with the world standard, TDA4863 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 TDA4863 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

优势:

简介

TDA4863属于集成电路（IC）的PFC（功率因数校正）。由制造生产的TDA4863PFC（功率因数校正）功率因数校正 (PFC) 是用于调整交流电路中的电压和电流之间的相位角，使之趋近于零的半导体器件。不同模式包括平均电流、边界导通、连续导通、临界导通、电流控制式频率折返、不连续和不连续导通，开关频率从 6 kHz 至 1.7 MHz 可调。
