UCC28070PWR TI Power Factor Correction | 20-TSSOP | Dual-Phase, 30kHz-300kHz

Product Overview

The UCC28070PWR from Texas Instruments is a high-performance, dual-phase interleaved power factor correction (PFC) controller designed for AC-DC power supplies requiring high efficiency and low total harmonic distortion (THD). Operating from a supply voltage of 10V to 21V, it integrates advanced features such as average current mode control, frequency dithering, and programmable switching frequency from 30kHz to 300kHz. The device is housed in a compact 20-pin TSSOP package, making it suitable for space-constrained applications.

Detailed Technical Specifications

Key Features

• Dual-phase interleaved operation for reduced input ripple and smaller magnetics
• Programmable frequency dithering for improved EMI performance
• Average current mode control with input feed-forward for fast transient response
• Comprehensive protection: overvoltage, overcurrent, open-loop, and thermal shutdown
• Low startup current (100µA typical) and low operating current (5mA typical)

Target Applications

• 5G base station power supplies (e.g., rectifier modules)
• Automotive dashboard power systems (e.g., infotainment power supplies)
• Industrial AC-DC converters for servers and telecom equipment
• LED lighting drivers requiring high power factor
• Home appliance power supplies (e.g., air conditioners, refrigerators)
