FAQs

What is UC2854BDW?

The UC2854BDW is a high-performance power factor correction (PFC) controller designed by Texas Instruments. It is specifically tailored for boost PFC applications in power supplies, lighting systems, and motor drives to improve power efficiency and comply with power quality standards.

How Does UC2854BDW Work?

The UC2854BDW operates by controlling the boost PFC converter to shape the input current waveform in phase with the input voltage, maximizing power factor and efficiency. It utilizes a control loop to adjust the duty cycle of the boost converter, ensuring the input current follows the input voltage in a sinusoidal manner, reducing harmonics and improving overall power quality.

How Many Pins does UC2854BDW have and What are the Functions of the Pinout Configuration?

The UC2854BDW comes in a 16-lead SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • VP, VN: Positive and negative power supply pins.
  • COMP, FB: Compensation and feedback pins for control loop stability.
  • HVCC, LVCC: High- and low-voltage controller supply pins.
  • CS, RT, CT: Current sense, timing resistor, and timing capacitor pins for setting operating parameters.
  • VREF, VFB: Reference voltage and feedback voltage pins.
  • EN, ENB: Enable and enable-bar pins for device activation.
