The UCC28083PWRG4 is a high performance cascaded 2-stage Power Factor Correction (PFC) controller with an integrated synchronous rectifier driver. This device is suitable for both single-stage and two-stage PFC applications in single-phase or three-phase systems. It has the capability of controlling a variety of power topologies such as Fly-Back, PFC Boost, and PFC+Inverter as well as providing enhanced protection features.

The UCC28083PWRG4 is classified as an AC/DC converter with offline switching that is capable of effectively regulating line voltage level while providing high efficiency and extensive system protection features. The device offers a wide input voltage range of up to 400V and an overload current of up to 4A.

The UCC28083PWRG4 utilizes a two-stage active PFC to provide AC/DC conversion while maintaining high efficiency and power factor correction. The Boost stage successfully compensates for any variation in the incoming line voltage and the PFC stage provides further power regulation, often improving system performance compared to single-stage AC/DC converters.

In addition, it supports a variety of protection features such as over-voltage protection (OVP) to guard against excessive input voltage, under-voltage protection (UVP) to provide a low-power shutdown, protection for output short-circuit, over-temperature protection (OTP) and thermal shutdown.

The UCC28083PWRG4 is appropriate for use in home appliances, office equipment, power tools, lighting fixtures and industrial equipment. The controller features robust performance and is adept at providing efficient power regulation and protection.
