• Operating Temperature Range: -40°C to +125°C
• Package: SO-16

Descriptions:

• The L6569 is a transition-mode (boundary conduction mode, BCM) PFC controller designed for boost converters.
• It ensures high power factor correction and low harmonic distortion in AC-DC power supplies.
• The device includes features for enhanced performance, such as precise output voltage regulation and protection mechanisms.

Features:

• Transition-Mode PFC Operation: Ensures high efficiency and low EMI.
• Multiplier-Based Control: Provides accurate input current shaping.
• Adjustable Output Voltage Regulation: Allows flexibility in design.
• Zero Current Detection (ZCD): Ensures operation in boundary conduction mode.
• Internal Startup Timer: Reduces external component count.
• Soft-Start Function: Minimizes inrush current.
• Overvoltage Protection (OVP): Prevents damage due to excessive output voltage.
• Under-Voltage Lockout (UVLO): Ensures proper startup and shutdown.
