L6563STR集成电路（IC）的PFC（功率因数校正）规格书PDF中文资料

L6563STR属于集成电路（IC）的PFC（功率因数校正）。由意法半导体集团制造生产的L6563STRPFC（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。

描述 Description

The L6563S is a current-mode PFC controller operating in transition mode (TM). Coming with the same pin-out as its predecessor L6563, it offers improved performance and additional functions.

特性 Features

■ Tracking boost function

■ Fast “bidirectional” input voltage feedforward (1/V2 correction)

■ Interface for cascaded converters PWM controller

■ Remote ON/OFF control

■ Accurate adjustable output overvoltage protection

■ Protection against feedback loop disconnection (latched shutdown)

■ Inductor saturation protection

■ Low (≤ 100 µA) start-up current

■ 6 mA max. operating bias current

■ 1 (@ TJ = 25 °C) internal reference voltage

■ -600/+800 mA totem pole gate driver with active pull-down during UVLO

■ SO14 package

Applications

PFC pre-regulators for:

■ High-end AC-DC adapter/charger

■ Desktop PC, server, Web server

■ IEC61000-3-2 or JEITA-MITI compliant SMPS, in excess of 400 W
