Power Factor Correction ICs

UCC2818MDREP Description

The UCC2818MDREP from Texas Instruments is a high-performance average current-mode power factor correction (PFC) controller designed for active PFC applications in AC/DC power supplies. Operating within a 12V to 17V supply range, this IC supports switching frequencies from 6kHz to 220kHz, making it versatile for various power conversion topologies. Packaged in a 16-SOIC and available in Tape & Reel (TR), it is optimized for surface-mount assembly and complies with ROHS3 and REACH environmental standards. With a low startup current of 150 µA, it ensures efficient power management in demanding applications.

UCC2818MDREP Features

• Average Current-Mode Control: Ensures high power factor (>0.99) and low THD (total harmonic distortion) for compliance with global efficiency standards.
• Wide Frequency Range (6kHz–220kHz): Enables flexible design for both low and high-frequency PFC stages.
• Low Startup Current (150 µA): Reduces power losses during initialization, improving system efficiency.
• Robust Protection: Features include overvoltage protection (OVP) and undervoltage lockout (UVLO) for enhanced reliability.
• Industry-Leading Packaging: 16-SOIC with MSL1 (Unlimited) moisture sensitivity ensures long-term storage stability.

UCC2818MDREP Applications

• Server & Telecom Power Supplies: Ideal for 80 PLUS Titanium-compliant designs requiring high efficiency.
• Industrial AC/DC Converters: Suitable for motor drives, welding equipment, and UPS systems.
• LED Lighting Drivers: Ensures stable power delivery with minimal harmonic distortion.
• Consumer Electronics: Used in high-power adapters and gaming consoles for improved power quality.

Conclusion of UCC2818MDREP

The UCC2818MDREP stands out as a high-efficiency, reliable PFC controller for modern power systems. Its average current-mode control, wide frequency range, and low startup current make it superior to conventional voltage-mode controllers. With TI's proven quality and compliance with ROHS3/REACH, it is an optimal choice for industrial, telecom, and consumer applications demanding high power factor and energy efficiency.
