Description

The L6562AT is a current-mode PFC controller operating in transition mode (TM). Coming with the same pin-out as its predecessors L6561 and L6562, it offers improved performance. The highly linear multiplier includes a special circuit, able to reduce AC input current distortion, that allows wide-range-mains operation with an extremely low THD, even over a large load range.

Features

■ Guaranteed for extreme temperature range (outdoor)

■ Proprietary multiplier design for minimum THD

■ Very accurate adjustable output overvoltage protection

■ Ultra-low (30 μA) start-up current

■ Low (2.5 mA) quiescent current

■ Digital leading-edge blanking on current sense

■ Disable function on E/A input

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

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

■ DIP-8/SO-8 packages
