Power Factor Correction ICs

UCC28512DW Description

The UCC28512DW from Texas Instruments is a high-performance average current-mode Power Factor Correction (PFC) controller designed for efficient AC/DC power conversion. Operating at a fixed switching frequency of 200kHz, it ensures stable and reliable performance in power supply designs. With a wide supply voltage range of 9.7V to 18V, this IC is optimized for industrial and commercial applications requiring compliance with power quality standards. Packaged in a 20-pin SOIC (DW) tube, it is RoHS3 compliant and rated for MSL 1 (unlimited) moisture sensitivity, making it suitable for automated assembly processes.

UCC28512DW Features

• Average Current-Mode Control: Ensures high power factor (>0.99) and low THD (Total Harmonic Distortion).
• Low Startup Current (100µA): Reduces power consumption during initial operation.
• Fixed 200kHz Switching Frequency: Simplifies EMI filter design and improves noise immunity.
• Wide Supply Range (9.7V–18V): Supports flexible input voltage conditions.
• Robust Protection: Includes overvoltage, undervoltage, and overcurrent safeguards.
• Surface-Mount (SOIC-20) Package: Ideal for compact, high-density PCB layouts.
• REACH Unaffected & EAR99 ECCN: Compliant with global environmental and export regulations.

UCC28512DW Applications

This PFC controller is ideal for:

• Server & Telecom Power Supplies: Enhances efficiency in 80Plus-compliant designs.
• Industrial AC/DC Converters: Ensures stable power delivery in harsh environments.
• LED Drivers: Improves power factor in high-brightness lighting systems.
• Consumer Electronics: Used in high-power adapters and appliances requiring PFC.
• Renewable Energy Systems: Optimizes grid-tied inverter performance.

Conclusion of UCC28512DW

The UCC28512DW stands out for its precision average current control, low startup current, and robust protection features, making it a superior choice for high-efficiency PFC stages. Its 200kHz fixed frequency operation reduces design complexity, while the wide supply range ensures versatility across applications. Engineers seeking a reliable, RoHS3-compliant PFC solution for industrial, telecom, or renewable energy systems will find this IC highly effective. Texas Instruments' reputation for quality further reinforces its suitability for demanding power electronics designs.
