Texas Instruments UCC28060 Natural Interleaved Dual-Phase Transition-Mode PFC Controller UCC28060DG4

The UCC28060DG4 is a Natural Interleaved Dual-Phase Transition-Mode Power Factor Correction (PFC) Controller designed by Texas Instruments. It operates within an input voltage range of 85-265VAC and is optimized for high-volume consumer applications, supporting power supplies from 100W to 800W. The controller features a dual-phase interleaving technique that enhances efficiency and reduces current ripple, leading to improved system reliability and smaller bulk capacitors. This device includes comprehensive system-level protections such as input brownout, output over-voltage, open-loop, overload, soft-start, phase-fail detection, and thermal shutdown. It also incorporates a FailSafe over-voltage protection feature to prevent catastrophic failures. The UCC28060DG4 is housed in a 16-pin SOIC package and operates over a temperature range of -40°C to +125°C. Its design allows for improved light-load efficiency and transient response, making it suitable for applications like LCD and plasma TVs, computer power supplies, entry-level servers, and electronic lighting ballasts.
