L6563STR集成電路（IC）的PFC（功率因數(shù)校正）規(guī)格書PDF中文資料

L6563STR屬于集成電路（IC）的PFC（功率因數(shù)校正）。由意法半導體集團制造生產(chǎn)的L6563STRPFC（功率因數(shù)校正）功率因數(shù)校正 (PFC) 是用于調(diào)整交流電路中的電壓和電流之間的相位角，使之趨近于零的半導體器件。不同模式包括平均電流、邊界導通、連續(xù)導通、臨界導通、電流控制式頻率折返、不連續(xù)和不連續(xù)導通，開關(guān)頻率從 6 kHz 至 1.7 MHz 可調(diào)。

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.

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
