Descriptions:

The L6560 is a high-performance PFC controller designed for boost-based power factor correction in AC/DC power supplies. It operates in Transition Mode (TM) to ensure high efficiency and low EMI. It features a multiplier-based control loop for near-unity power factor and low THD (Total Harmonic Distortion).

Features:

• High Power Factor (>0.99)
• Low THD (Total Harmonic Distortion)
• Zero-Current Detection (ZCD) for TM operation
• Internal Start-Up Timer
• Precision Voltage Reference (2.5V ±1%)
• Adjustable Output Overvoltage Protection
• DIP-8 and SO-8 package options

The L6560 is commonly used in SMPS (Switched-Mode Power Supplies), LED drivers, and offline power supplies requiring compliance with power quality standards (e.g., IEC 61000-3-2).
