UCC28070PWR Typical application Circuitry

UCC28070PWR

The UCC28070PWR is an advanced, multi-phase interleaved Power Factor Correction (PFC) controller integrated circuit (IC) developed by Texas Instruments. This device is designed to efficiently handle power supply systems in applications that require high power factor correction and high efficiency.

Key Features:

1. Multi-Phase Interleaved PFC: The UCC28070PWR is capable of operating in a multi-phase configuration, allowing several channels to work in an interleaved manner. This reduces input and output ripple currents and enhances system performance and reliability.

2. Continuous Conduction Mode (CCM): It operates in continuous conduction mode, which is suitable for applications requiring high efficiency and high power factor.

3. Programmable Phase Management: The device allows the addition or removal of active phases based on load conditions, thereby optimizing efficiency across a wide range of loads.

4. Variable Frequency Operation: The UCC28070PWR uses variable-frequency continuous conduction mode (VF-CCM) to achieve high efficiency while maintaining low total harmonic distortion (THD).

5. Current Sharing: It employs techniques for precise current sharing among the phases, which is critical for optimizing performance and ensuring system reliability.

6. Wide Input Voltage Range: It can operate over a wide range of input voltages, making it suitable for universal AC input power supplies.

7. Protection Features: The device incorporates multiple protection features such as over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), and brownout protection to ensure safe and reliable operation.

8. Efficiency Enhancement: By dynamically adding or shedding phases, the UCC28070PWR can maintain high efficiency over a broad load range.

9. Package: The "PWR" in the part number indicates that the device is available in a TSSOp(Thin Shrink Small Outline Package).

10. Applications: This IC is suitable for high-performance applications requiring power factor correction and high efficiency, such as server and telecom power supplies, air conditioners, industrial power supplies, and LED lighting.

To obtain a comprehensive understanding including electrical characteristics, pin configurations, timing diagrams, and application guidelines, it's recommended to consult the datasheet for the UCC28070PWR.
