UCC28061DR Typical application Circuitry

UCC28061DR

The UCC28061DR is part of Texas Instruments' UCC28061 series, a family of transition-mode PFC (Power Factor Correction) controllers. This integrated circuit is specifically designed for use in pre-regulators of off-line power supplies, aimed at improving power factor and reducing harmonic distortion. The UCC28061DR is frequently utilized in applications like AC-to-DC adapters, televisions, and power supplies for desktops and servers, where efficient and reliable power delivery is essential.

1. Power Supply and Voltage Sensing: The UCC28061DR requires a supply voltage connected to the VCC pin. Additionally, it involves the connection of voltage sensing pins (VS1 and VS2) to the rectified AC mains voltage. These pins are crucial for monitoring the input voltage waveform and enabling the device to adjust the power factor accordingly.

2. Ground Connection: The GND pin should be connected to the system's ground. This is essential for the stability and reference of the controller's internal operations.

3. Current Sensing and Drive Outputs: The UCC28061DR features current sensing inputs (CS1 and CS2) that connect to shunt resistors for detecting the inductor current. Drive outputs (DRV1 and DRV2) are connected to the gates of external MOSFETs, controlling the switching of the power factor correction circuit.

4. Frequency Synchronization and Clock: The device includes a clock output (CLKOUT) and a synchronization input (SYNC), allowing multiple UCC28061DR controllers to synchronize their switching frequencies in multi-phase systems.

5. Error Amplifier and Feedback: The UCC28061DR has an error amplifier input (COMP) for closed-loop control. This pin is typically connected to a feedback network from the output voltage, ensuring the output is regulated accurately according to the desired set point.

6. Soft-Start and Disable: The SS/DISB pin is used for soft-start functionality to prevent inrush current at startup and can also be used to disable the device if necessary.

7. Oscillator Adjustments: The RT pin connects to a resistor for setting the switching frequency of the controller. This allows the designer to optimize the performance of the power factor correction circuit.

8. ZCD and ZVS Inputs: The Zero-Current Detection (ZCD) and Zero-Voltage Switching (ZVS) inputs are crucial for improving the efficiency of the power factor correction by reducing switching losses.

9. Thermal Management: Considering the power handling involved, thermal management must be addressed in the PCB design, ensuring that the UCC28061DR operates within its temperature limits.

10. PCB Layout Considerations: The layout is critical, especially for the high-current paths and switching nodes. Minimizing trace inductances and optimizing the layout for thermal performance are key to the successful implementation of the UCC28061DR in a power factor correction application.

In summary, the integration of the UCC28061DR into a power supply system requires careful consideration of power supply connections, voltage and current sensing, drive outputs, synchronization, feedback control, soft-start capabilities, oscillator settings, and thermal management, all within a well-planned PCB layout. These considerations ensure the UCC28061DR operates effectively as a PFC controller, enhancing the power efficiency and stability of the application it serves.
