STMicroelectronics | L6562ATD

The L6562ATD 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

Applications:

• PFC pre-regulators for:
• Street lighting
• IEC61000-3-2 compliant SMPS (Flat TV, monitors, desktop PC, games)
• Electronic ballast
