L6562ADTR 功率因数校正

L6562ADTR

功率因数校正 - PFC HV H-Bridge driver Transition-mode PFC controller

Description L6562ADTR

The L6562A 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 L6562ADTR

■ Proprietary multiplier design for minimum THD

■ Very accurate adjustable output overvoltage

protection

■ Ultra-low (30μA) Start-up current

■ Low (2.5mA) quiescent current

■ Digital leading-edge blanking on current sense

■ Disable function on E/A input

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

■ -600/+800mA totem pole gate driver with active

pull-down during UVLO and voltage clamp

■ DIP-8/SO-8 packages

Applications L6562ADTR

PFC pre-regulators for:

■ IEC61000-3-2 compliant SMPS (Flat TV,

monitors, desktop PC, games)

■ HI-END AC-DC adapter/charger up to 400W

■ Electronic ballast

■ Entry level server & web server
