L6563TR Datasheet

Power Factor Correction ICs


The L6563TR device is a current-mode PFC controller operating in Transition Mode (TM). Based on the core of a standard TM PFC controller, it offers improved performance and additional functions.The highly linear multiplier, along with a special correction circuit that reduces crossover distortion of the mains current, allows wide-range-mains operation with an extremely low THD even over a large load range. L6563TR Features • Transition-mode control of PFC pre-regulators• Very precise adjustable output overvoltage protection• Tracking boost function• Protection against feedback loop failure (Latched shutdown)• Interface for cascaded converters PWM controller• Input voltage feedforward (1/V2)• Remote ON/OFF control• Low (≤90μA) start-up current• 5mA max. quiescent current L6563TR Applications • PFC pre-regulators for:• HI-END AC-DC adapter/charger• Desktop PC, server, WEB server• IEC61000-3-2 OR JEIDA-MITI compliant SMPS, in excess of 250W
