L6563H
High voltage start-up transition-mode PFC
Features
■ On-board 700 V start-up source
■ Tracking boost function
■ Fast “bidirectional” input voltage feedforward
(1/V2 correction)
■ Interface for cascaded converter's 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
SO16
SO-16
Applications
PFC pre-regulators for:
■ Hi-end AC-DC adapter/charger
