UCC28712DR Description
The UCC28712DR is made by Texas Instrument, a primary-side regulated flyback controller for high-density AC/DC power supplies. This integrated circuit (IC) is designed to work with both isolated and non-isolated AC/DC power sources, making it suitable for use in a wide range of applications.
The UCC28712DR includes several features that make it an attractive option for power supply designers. For example, it has low standby power consumption, which helps to meet energy efficiency standards. It also includes advanced protection features such as overvoltage protection, overcurrent protection, and overtemperature protection, which help to ensure safe and reliable operation.
The UCC28712DR uses primary-side regulation (PSR) to regulate the output voltage, which simplifies the design of the power supply by eliminating the need for optocouplers or secondary-side feedback circuitry. This can lead to a smaller, more efficient, and lower cost power supply.
