Texas Instruments UCC28060 Natural Interleaved Dual-Phase Transition-Mode PFC Controller UCC28060D

The UCC28060D is a Natural Interleaved Dual-Phase Transition-Mode Power Factor Correction (PFC) Controller designed for high-efficiency applications in power supplies ranging from 100 W to 800 W. It operates with an input voltage range of 85-265 VAC and is optimized for consumer electronics, including LCD and plasma TVs, computer power supplies, and electronic lighting ballasts. This controller features a dual-phase interleaving technique that enhances efficiency and reduces current ripple, leading to improved system reliability and smaller bulk capacitors. It includes comprehensive system-level protections such as input brownout, output over-voltage, open-loop, overload, soft-start, phase-fail detection, and thermal shutdown. The FailSafe over-voltage protection prevents catastrophic failures due to voltage-sensing issues. The UCC28060D is housed in a 16-pin SOIC package and operates over a temperature range of -40°C to +125°C. It is suitable for applications requiring high performance and efficiency while maintaining cost-effectiveness through the use of low-cost components.
