The UCC28512DWG4 is one of the most popular power factor correction (PFC) devices in the integrated circuit (IC) industry. This controller can be used for a variety of applications ranging from kilowatt to multi-kilowatt applications. The primary function of this controller is to regulate input power factor with an output of a single-phase bridge circuit or a three-phase bridge circuit with power factor correction.

A power factor is the ratio of true power to apparent power. It is typically measured in either a single-phase or three-phase system. It is desired to keep the power factor at its maximum level (1.00) since this will make the most efficient use of electrical power. The UCC28512DWG4 controller is used to achieve this goal by providing active power factor correction.

The UCC28512DWG4 controller works by comparing the output voltage and current waveforms of the PFC circuit. When the wave forms do not match, the controller ensures that the wave forms are forced to match. This is accomplished by modulation of the input voltage and adjusting the current through the output circuit.

The UCC28512DWG4 features several features that make it an attractive choice for applications requiring power factor correction. These features include an adjustable power factor correction range from 85% to 99%, ±12V operation, protective functions such as over-temperature and over-voltage protection, Soft-Start with an externally adjustable delay, and very low power consumption. The UCC28512DWG4 also offers up to 1MHz operation for quick response times and improved power correct ability.

The UCC28512DWG4 has a wide range of applications, from low power converters to high power supplies. It can be used in switching power supplies, DC/DC converters, and AC/DC power supplies. It can also be used in products such as audio amplifiers and data converters, where improved power factor is desired.

The UCC28512DWG4 is an excellent choice for power factor correction applications. Its adjustable range and low power consumption make it well suited for any application that requires a solution for improved electrical efficiency. The advanced protective functions and superior performance make it a reliable and cost-effective choice for any application that requires power factor correction.
