UCC28050DR

Overview

The UCC28050DR is a transition mode power factor correction (PFC) controller manufactured by Texas Instruments. It operates within a switching frequency range of 200 kHz and supports surface-mount installation in an SOIC-8 package. The device functions reliably across a temperature range from -40°C to +85°C, with a typical operating supply current of 75 µA.

Feature Summary

• Transition mode PFC control architecture
• Integrated high-voltage startup circuit
• Low standby supply current consumption

Applications

• Adaptive power supplies
• LCD TV backlight drivers
• Computer peripheral power supplies

Procurement Notes

Verify the specific suffix 'DR' indicates the tape-and-reel packaging variant when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the SOIC-8 thermal requirements for the intended application environment.

Selection Notes

Select this component for designs requiring simplified transition mode PFC implementation. Consider the 200 kHz switching frequency limit and SOIC-8 package constraints during layout planning. Evaluate the low quiescent current benefit against system efficiency targets.

Part Context

This part belongs to the UCC28050 series of power factor correction controllers. It is designed as a cost-effective solution for single-stage power factor correction applications where high efficiency at light loads is required.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family if lead times are critical. Verify functional equivalence regarding startup voltage and switching frequency limits before substitution.
