UCC28061DRG4 Typical application Circuitry

UCC28061DRG4

The UCC28061DRG4 is a specialized integrated circuit in Texas Instruments' UCC28061 series, designed for power factor correction (PFC) applications. As a transition-mode PFC controller, the UCC28061DRG4 is engineered to enhance power efficiency in AC-DC power supplies, particularly in systems where power factor correction is a requirement. Common applications include consumer electronics, such as televisions and computer monitors, as well as industrial power systems.

1. Power Supply and Voltage Sensing: The UCC28061DRG4 needs a power supply connected to the VCC pin. This IC also has voltage sensing pins (VS1 and VS2), which are connected to the rectified AC mains voltage. These pins are crucial for the controller to sense the input voltage waveform and manage the power factor correction accordingly.

2. Grounding Connection: Connect the GND pin to the system's ground. This connection is vital for the stable operation of the UCC28061DRG4 and provides a common reference for all internal circuits.

3. Current Sensing for Control: The IC features current sensing inputs (CS1 and CS2), which are typically connected to sense resistors in the power path. These inputs allow the UCC28061DRG4 to monitor the current and control the PFC process effectively.

4. Drive Output Pins: The DRV1 and DRV2 pins are the drive outputs of the UCC28061DRG4, which connect to the gates of external power MOSFETs. These pins are responsible for switching the MOSFETs in accordance with the PFC control strategy.

5. Frequency Synchronization: The device includes a clock output (CLKOUT) and a synchronization input (SYNC). These pins allow multiple UCC28061DRG4 units to synchronize their switching frequencies in applications requiring multi-phase PFC.

6. Feedback and Error Amplification: An error amplifier input (COMP) is provided for feedback control. This pin connects to a voltage divider from the output, helping to maintain accurate output voltage regulation.

7. Soft-Start and Shutdown Control: The SS/DISB pin serves dual purposes – it controls the soft-start functionality to limit inrush current at power-up and can also be used to disable the controller.

8. Oscillator Configuration: The RT pin is used to set the oscillator frequency by connecting an external resistor. This adjustment is crucial for optimizing the performance of the PFC circuit.

9. Zero-Current and Zero-Voltage Detection: The ZCD (Zero-Current Detection) and ZVS (Zero-Voltage Switching) inputs are essential for improving efficiency by minimizing switching losses.

10. Thermal and Layout Considerations: Given the power processing involved, appropriate thermal management is crucial. Additionally, the PCB layout should be carefully designed to minimize trace inductances and optimize heat dissipation.

Incorporating the UCC28061DRG4 into a power supply system involves attention to detail in terms of power supply connections, voltage and current sensing, output drive, synchronization, feedback mechanisms, soft-start and shutdown functionalities, oscillator tuning, zero-current and voltage detection, and thermal management within a carefully designed PCB layout. This careful integration ensures that the UCC28061DRG4 effectively performs its role in power factor correction, enhancing the efficiency and stability of the power supply.
