L6562D** is a current-mode PFC controller IC manufactured by **STMicroelectronics (ST)**.

The L6562D is a current-mode PFC controller IC manufactured by STMicroelectronics (ST). Below are the factual specifications, descriptions, and features:

Specifications:

  • Manufacturer: STMicroelectronics
  • Type: Transition-Mode PFC Controller
  • Package: SO-8
  • Input Voltage Range (VCC): 10.5V to 22V
  • Operating Frequency: Up to 300kHz
  • Start-up Current: < 70μA
  • Quiescent Current: < 4mA
  • Output Drive Current (Gate Driver): ±400mA (sink/source)
  • Reference Voltage (VREF): 2.5V ±1%
  • Overvoltage Protection (OVP): Yes
  • Undervoltage Lockout (UVLO): Yes
  • Operating Temperature Range: -40°C to +125°C

Description:

The L6562D is a high-performance, transition-mode (boundary conduction mode) power factor correction (PFC) controller. It is designed for pre-regulators in AC-DC adapters, LED drivers, and SMPS applications. It ensures compliance with EN61000-3-2 standards for harmonic current emissions.

Features:

  • Transition-Mode Operation: Ensures high power factor (>0.99) and low THD.
  • Multiplier with Improved Line Feedforward: Enhances input voltage regulation.
  • Zero Current Detection (ZCD): Enables boundary conduction mode operation.
  • Programmable Output Overvoltage Protection (OVP): Protects against excessive output voltage.
  • Low Start-up and Operating Current: Reduces power consumption.
  • Enhanced EMI Performance: Minimizes switching noise.
  • Disable Function: Allows remote ON/OFF control.

For detailed application notes and circuit examples, refer to the official STMicroelectronics datasheet.
