L6562A Transition-mode PFC Controller IC (SMD Package)

Description

The L6562A is a current-mode PFC controller that operates in Transition Mode (TM). It delivers better performance while having the same pin-out as its predecessors, the L6561 and L6562. The very linear multiplier has a unique circuit that can lessen the distortion of the AC input current and enable wide-range mains operation with a very low THD, even over a wide load range.
A voltage-mode error amplifier and a precise (1 percent @TJ = 25°C) internal voltage reference are used to control the output voltage.
It is easy to comply with energy conservation regulations thanks to the device's exceptionally low consumption (60 A max. before start-up and 5 mA operating) and disable function appropriate for IC remote ON/OFF (Blue Angel, EnergyStar, Energy2000, etc.).

Features

• 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

Applications

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
