常見問題解答

What is UCC28600D?

The UCC28600D is a green-mode flyback PWM controller designed by Texas Instruments. It is specifically designed for offline AC/DC power supplies and provides highly efficient, low standby power, and low system cost solutions.

How Does UCC28600D Work?

The UCC28600D operates by controlling the power switch duty cycle in response to the instantaneous input line voltage and the output load. It utilizes a pulse frequency modulation (PFM) and frequency foldback scheme to provide high efficiency over a wide load range. The controller also features green-mode operation to minimize standby power consumption and meet energy efficiency standards.

How Many Pins does UCC28600D have and What are the Functions of the Pinout Configuration?

The UCC28600D is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • VDD: Power supply pin for the controller.
  • FB: Feedback input pin for output voltage regulation.
  • CS: Current sense input pin for cycle-by-cycle overcurrent protection.
  • COMP: Compensation pin for loop stability and/or slope compensation.
  • DRV: Gate driver output pin for the external MOSFET.
  • RT/CLK: Pin for setting the switching frequency and soft start time.
  • SD: Shutdown pin for enabling/disabling the controller.
  • GND: Ground pin.

What are the Pros and Cons of UCC28600D?

Pros:

  • High Efficiency: Provides high efficiency through PFM and frequency foldback schemes.
  • Green-Mode Operation: Minimizes standby power consumption to meet energy efficiency standards.
  • Low System Cost: Offers cost-effective solutions for AC/DC power supplies.
  • Compact Package: The 8-pin SOIC package is space-efficient, suitable for compact designs.
  • Protection Features: Includes cycle-by-cycle overcurrent protection for enhanced reliability.

Cons:

  • External Components: May require additional external components for optimal performance in specific applications.
  • Design Complexity: Requires careful design considerations for loop stability and slope compensation.
  • Application Specific: Designed specifically for offline AC/DC power supplies, may not be suitable for other applications.

Are There Any Equivalents/Alternatives to UCC28600D for Recommendation?

  • The UCC28700 from Texas Instruments is a similar green-mode flyback PWM controller with enhanced features.
  • Alternatives to the UCC28600D include the FSCQ1565RT from Power Integrations and the ICE5QSAG from Infineon Technologies.
