UCC28740DR Typical application Circuitry

UCC28740DR

The UCC28740DR is an advanced flyback controller integrated circuit (IC) developed by Texas Instruments. This IC is designed to regulate and control secondary-side power delivery in isolated power supplies, and it is optimized for high efficiency, low standby power, and excellent dynamic response.

Key Features:

1. Secondary-Side Regulation: The UCC28740DR provides precise regulation by controlling power delivery from the secondary side of an isolated power supply. This improves transient response and overall system reliability.

2. Constant-Voltage and Constant-Current (CV/CC) Regulation: It provides accurate CV/CC regulation, making it suitable for battery charging and LED lighting applications.

3. Opto-Coupler Elimination: This device uses a proprietary isolated-feedback sensing and communication method that eliminates the need for an opto-coupler, thereby enhancing reliability and longevity.

4. High Efficiency: It is designed for high efficiency, especially in light-load conditions, which is critical for meeting power consumption standards such as Energy Star.

5. Green-Mode Operation: The UCC28740DR features a green-mode operation that enables low standby power consumption.

6. Protection Features: The device incorporates multiple protection features, such as over-voltage protection (OVP), over-current protection (OCP), over-temperature protection (OTP), and short-circuit protection to ensure safe operation.

7. Zero Power Detection: It includes a zero power detection feature that helps in minimizing the standby power consumption of the overall system.

8. Package: The "DR" in the part number indicates that the device is available in an SOIC (Small Outline Integrated Circuit) package.

9. Wide Voltage Range: The UCC28740DR can handle a wide range of input and output voltages, making it suitable for versatile applications.

10. Applications: This IC is ideal for a variety of applications such as AC/DC adapters, battery chargers, LED lighting drivers, smart meter power supplies, and other isolated power conversion solutions.

For detailed information including electrical characteristics, pin configurations, timing diagrams, and application guidelines, it's recommended to consult the datasheet for the UCC28740DR.
