UCC28060DG4

Overview

The UCC28060DG4 is a single-chip interleaved power factor correction controller from Texas Instruments, designed for multi-kilowatt communications, server, and industrial systems. It utilizes two-phase average current-mode control to achieve a power factor rating greater than 0.9, improving energy efficiency. The device features an advanced current synthesizer for superior efficiency and accurate sensing, alongside a highly linear multiplier output with internal voltage feed-forward correction. Key specifications include a switching frequency of 500 kHz, a supply voltage range of 8V to 21V, and operation within a temperature range of -40°C to 125°C in a 16-SOIC package.

Feature Summary

• Interleaved average current mode PWM control for simplified power design
• Advanced current synthesizer ensuring accurate current sensing and high power factor
• Internal voltage feed-forward correction for near unity power factor performance

Applications

• Multi-kilowatt communication systems
• Server power supplies
• Industrial system power management

Procurement Notes

Verify the specific suffix DG4 against the manufacturer's official documentation to confirm RoHS compliance and lead-free status. Ensure the component matches the 16-SOIC physical package dimensions and pinout configuration required by the target PCB layout. Cross-reference the part number with the latest datasheet to confirm availability status, as discontinuation notices may affect long-term sourcing strategies.

Selection Notes

Select this controller when designing high-power applications requiring natural interleaving to reduce input ripple and improve thermal distribution. It is suitable for designs needing average current mode control without external phase management complexity. Consider the 500 kHz fixed switching frequency and the wide operating temperature range when evaluating thermal constraints and electromagnetic interference requirements for the final system architecture.
