L6560** is a **Power Factor Corrector (PFC) controller** manufactured by **STMicroelectronics**.

The L6560 is a Power Factor Corrector (PFC) controller manufactured by STMicroelectronics.

Key Specifications:

  • Input Voltage Range: 10V to 20V (VCC supply)
  • Operating Frequency: Up to 300 kHz
  • Output Drive Capability: 600 mA source / 800 mA sink
  • PFC Operation: Transition Mode (TM) / Boundary Conduction Mode (BCM)
  • Start-Up Current: < 100 µA
  • Standby Power Consumption: < 1W
  • Protection Features:
  • Overvoltage Protection (OVP)
  • Undervoltage Lockout (UVLO)
  • Open-Loop Protection
  • Soft-Start Function

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).

For detailed electrical characteristics, refer to the official STMicroelectronics datasheet.
