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.
