L6561D** is a transition-mode PFC (Power Factor Correction) controller manufactured by **STMicroelectronics (ST)**.

The L6561D is a transition-mode PFC (Power Factor Correction) controller manufactured by STMicroelectronics (ST).

Key Specifications:

  • Input Voltage Range: 85V to 265V AC
  • Output Voltage Range: Up to 400V DC
  • Operating Frequency: Up to 300kHz
  • Startup Current: < 100µA
  • Quiescent Current: < 4mA
  • Driver Output Current: ±400mA (peak)
  • Supply Voltage (VCC): 10.5V to 22V
  • Protections:
  • Overvoltage Protection (OVP)
  • Undervoltage Lockout (UVLO)
  • Open-Loop Protection
  • Package: SO-8

Descriptions:

The L6561D is designed for transition-mode (boundary conduction mode, BCM) power factor correction in AC-DC converters. It ensures high power factor (>0.99) and low harmonic distortion, complying with international standards like IEC 61000-3-2.

Features:

  • Zero-current detection for transition-mode operation
  • Multiplier with improved linearity for wide input range
  • Precision voltage reference (2.5V ±1%)
  • Adjustable output overvoltage protection
  • Low power consumption in standby mode
  • Totem-pole output driver for MOSFET/IGBT control

The L6561D is commonly used in SMPS (Switched-Mode Power Supplies), LED drivers, and adapters requiring high efficiency and power factor correction.
