UCC28060DR

Overview

The UCC28060DR is a natural interleaved dual-phase transition-mode power factor correction (PFC) controller manufactured by Texas Instruments. It operates within a supply voltage range of 14V to 21V and supports switching frequencies up to 500 kHz. The device is housed in a 16-pin SOIC package and functions reliably across an extended temperature range from -40°C to +125°C. Designed for high-efficiency applications, it complies with light-load efficient standards while offering improved design flexibility over traditional single-phase continuous conduction mode solutions.

Feature Summary

• Implements natural interleaving technique for dual-phase transition-mode PFC control
• Complies with light-load efficiency standards to reduce standby power consumption
• Provides enhanced design flexibility compared to traditional single-phase continuous conduction mode controllers

Applications

• High-efficiency power factor correction stages in AC-DC converters
• Power supplies requiring compliance with strict light-load energy efficiency regulations
• Dual-phase interleaved PFC designs for improved thermal distribution and ripple cancellation

Procurement Notes

Verify the specific ordering suffix 'D' corresponds to the SOIC-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected component matches the required operating temperature range specifications for your intended environment. Cross-reference the datasheet revision history to validate feature availability and electrical characteristics against your design requirements.

Selection Notes

Select this controller for applications demanding dual-phase interleaving without complex digital control loops. It is suitable for designs prioritizing natural phase shifting to minimize input current ripple. Consider this part when transitioning from single-phase CCM topologies to achieve better efficiency at partial loads. Evaluate thermal management needs as dual-phase operation distributes heat across two channels.

Part Context

This component belongs to the UCC2806x series of PFC controllers from Texas Instruments. It is specifically engineered for transition-mode operation with natural interleaving capabilities. The DR suffix indicates the tape-and-reel packaging format for surface-mount assembly. It serves as a specialized solution for high-performance power factor correction in modern electronic equipment.

Replacement Considerations

The UCC28060D is the tube-packaged equivalent of the UCC28060DR. Designers may substitute based on manufacturing assembly preferences, provided the functional specifications remain identical. Verify that the package footprint and pinout are compatible with the existing PCB layout before swapping between reel and tube variants.
