UCC28070PWR

The UCC28070PWR is a dual-phase, interleaved, boost Power Factor Correction (PFC) controller designed by Texas Instruments. It aims to improve power quality by controlling power factor and reducing harmonics in AC-DC conversion systems. The device operates by interleaving two boost converters, effectively spreading the current across phases to reduce input and output current ripple, leading to smaller filter components and improved efficiency.
Key features of the UCC28070PWR include Continuous Conduction Mode (CCM) operation, advanced load transient response, and current balancing between phases to ensure equal current sharing. It supports a wide input voltage range and incorporates various protection features, such as overvoltage protection, under-voltage lockout, and overcurrent protection, enhancing system reliability and safety.
The UCC28070PWR is suitable for high-power applications, including industrial power supplies, server power supplies, and other systems requiring efficient power factor correction and high power density. Its thermally enhanced PowerPAD™ package aids in heat dissipation, making it suitable for compact and efficient power supply designs.
