Description

The IR1150S is a high-performance One Cycle Control (OCC) Power Factor Correction (PFC) IC designed by Infineon Technologies. It is specifically built for boost-type PFC converters in continuous conduction mode (CCM). This IC provides precise power factor correction with minimal external components, making it ideal for high-efficiency applications such as power supplies, LED drivers, and industrial equipment.

Features

  • Power Factor Correction:
    • High power factor (close to 1) and low total harmonic distortion (THD).
  • One Cycle Control:
    • Provides fast transient response and eliminates the need for external voltage loop compensation.
  • Wide Operating Range:
    • Supports universal AC input voltage (85-265V).
  • Integrated Protection Features:
    • Over-voltage protection (OVP).
    • Cycle-by-cycle peak current limit.
    • Input brown-out protection.
    • Soft-start for reduced inrush current.
  • Low Standby Power Consumption:
    • Optimized for energy-efficient designs.
  • High Switching Frequency:
    • Operates up to 200 kHz, enabling compact designs with smaller passive components.
  • Compact Package:
    • Available in an SMD SOIC-8 package for easy PCB integration.

Specifications

Electrical Characteristics
  • Input Voltage: 85-265V AC (universal AC input).
  • Output Voltage: Adjustable PFC boost voltage.
  • Switching Frequency: Up to 200 kHz.
  • Current Sense Input Range: 0.25V to 2.5V.
  • Standby Current: <1 mA.
Protection Features
  • Over-Voltage Protection (OVP): Protects the system from excessive output voltage.
  • Over-Current Protection (OCP): Limits peak current in the PFC inductor.
  • Brown-Out Protection: Disables operation during low input voltage to prevent damage.
  • Soft-Start: Gradual increase in output to avoid inrush current.
