The MC33260P is a power factor correction (PFC) controller IC manufactured by ON Semiconductor. Below are the factual details about its specifications, descriptions, and features:

Specifications:

• Manufacturer: ON Semiconductor
• Package: PDIP-8 (Plastic Dual In-Line Package)
• Operating Voltage Range: 10V to 16V (typical)
• Start-Up Voltage: 12V (typical)
• Quiescent Current: 4mA (typical)
• Switching Frequency: Adjustable (typically up to 250kHz)
• Operating Temperature Range: -40°C to +105°C
• Maximum Duty Cycle: 94% (typical)

Descriptions:

• The MC33260P is a transition-mode PFC controller designed for boost converter applications.
• It operates in critical conduction mode (boundary between continuous and discontinuous conduction) to improve power factor.
• The IC includes features for overvoltage protection (OVP), undervoltage lockout (UVLO), and soft-start functionality.

Features:

• Power Factor Correction (PFC): Ensures high power factor (>0.99) in AC-DC applications.
• Zero-Current Detection (ZCD): Enables transition-mode operation for improved efficiency.
• Internal Startup Timer: Reduces external component count.
• Low Distortion: Minimizes input current harmonic distortion.
• Overvoltage Protection (OVP): Safeguards against excessive output voltage.
• Undervoltage Lockout (UVLO): Prevents operation below the minimum supply voltage.
• Soft-Start Function: Reduces inrush current during startup.
• Adjustable Output Voltage: Allows flexibility in design.
