UCC28502DWG4

Overview

The UCC28502DWG4 is a Power Factor Correction (PFC) integrated circuit 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 package and is designed for industrial applications within an operating temperature range of -40°C to 85°C.

Feature Summary

• Implements average current mode control for PFC applications
• Integrates cycle-by-cycle peak current limiting
• Includes programmable soft-start functionality

Applications

• Power factor correction stages in AC-DC power supplies
• Industrial power conversion systems
• High-efficiency switched-mode power supplies

Procurement Notes

Verify the specific suffix 'G4' indicates compliance with RoHS3 standards as documented in official specifications. Confirm that the SOIC-20 package dimensions match the design requirements. Ensure the component meets the required thermal performance for the intended operating environment.

Selection Notes

Select this component for designs requiring average current mode PFC control at 100 kHz. It is suitable for applications needing a wide input voltage range and robust protection features. Consider the 20-SOIC package for surface-mount assembly constraints.

Part Context

This part belongs to the UCC2850x series of PFC controllers from Texas Instruments. It shares functional similarities with other members of the family but differs in package type and specific pinout configuration. The DWG4 variant specifically denotes the SOIC package and environmental compliance.
