Overview
The IR1150PBF is a Power Factor Correction (PFC) controller utilizing Universal PFC (UPFC) One Cycle Control technology. It integrates a high-voltage current source for biasing, eliminating the need for auxiliary windings. The device supports universal AC input ranges and includes brown-out protection with hysteresis. It operates in continuous conduction mode to regulate output voltage and improve power factor efficiency.
Feature Summary
- Integrates UPFC One Cycle Control architecture for simplified circuit design
- Features an integrated high-voltage current source for self-biasing
- Includes programmable brown-out protection with hysteresis
- Supports universal AC line input voltage ranges
Applications
- Desktop switch-mode power supplies
- Server power supply units
- AC-DC adapters
- Telecommunications power systems
Procurement Notes
Verify the specific suffix against official Infineon documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lifecycle stage, as older International Rectifier designs may have discontinued variants or alternative packaging options available from distributors.
Selection Notes
Select this component for applications requiring high power factor correction without complex feedback loops. The integrated bias source reduces external component count. Ensure the design accommodates the required operating temperature range and validates thermal performance under maximum load conditions specified in the datasheet.
Part Context
Originally developed by International Rectifier, now part of Infineon Technologies. This component belongs to the family of single-stage PFC controllers designed for cost-effective power conversion. It bridges the gap between simple boost converters and more complex multi-stage solutions.
Replacement Considerations
Consult official Infineon substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully when considering legacy replacements from other manufacturers.
