Overview
The UCC28502DWTRG4 is a Power Factor Correction (PFC) controller IC manufactured by Texas Instruments. It operates in average current mode with a switching frequency of 100 kHz. The device supports a supply voltage range of 9.7V to 18V and features a startup current of 150 µA. It is housed in a 20-SOIC surface-mount package and is rated for an operating temperature range of -40°C to 85°C. This component is part of the UCC28500-03 series.
Feature Summary
- Implements average current mode control for power factor correction applications
- Integrated cycle-by-cycle current limiting protection
- Supports high-frequency operation at 100 kHz switching rate
Applications
- Power factor correction stages in AC-DC power supplies
- Universal input offline power converters
- Industrial and commercial power management systems
Procurement Notes
Verify the specific suffix 'DWTRG4' against the manufacturer's official documentation to confirm the tape-and-reel packaging and RoHS compliance status. Confirm that the 20-SOIC package dimensions match your PCB footprint requirements. Ensure the supply voltage range of 9.7V to 18V aligns with your system design constraints before procurement.
Selection Notes
Select this component when average current mode PFC control is required with a fixed 100 kHz switching frequency. It is suitable for designs needing a 20-pin SOIC package for surface-mount assembly. Verify that the 9.7V to 18V supply range fits the application's Vcc requirements. Consider the -40°C to 85°C operating temperature range for environmental compatibility.
Part Context
The UCC28502DWTRG4 belongs to the UCC28500-03 family of PFC controllers from Texas Instruments. These devices are designed for high-performance power factor correction in offline power supplies. The family typically includes variants with different packages and suffixes, such as the DIP version UCC28502N. The DWTRG4 variant specifically denotes the surface-mount SOIC package with tape-and-reel delivery.
Replacement Considerations
