This document describes the features of the L6562AT transition-mode PFC controller released in March 2009, including guaranteed performance for extreme temperature range, proprietary multiplier design for minimum THD, very accurate adjustable output overvoltage protection, ultra-low start-up current, low quiescent current, digital leading-edge blanking on current sense, disable function on E/A input, 1% internal reference voltage, -600/+800 mA totem pole gate driver with active pull-down, and its applications in PFC pre-regulators such as street lighting and IEC61000-3-2 compliant SMPS (Flat TV, monitors, desktop PC, games).
The L6562AT is a current-mode Power Factor Correction (PFC) controller operating in transition mode. It is designed for applications requiring EN61000-3-2 compliance, such as street lighting and SMPS for flat TVs and desktop PCs. The device features a proprietary multiplier design to minimize Total Harmonic Distortion (THD) and includes an accurate internal voltage reference.
