UCC2803D Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the UCC2803D is 500 kHz, but it can be operated at higher frequencies with reduced performance.
  • To ensure stable operation, it is recommended to use a minimum output capacitance of 10uF, and to decouple the input and output pins with 0.1uF capacitors. Additionally, a 1kΩ resistor should be connected between the VCC and GND pins.
  • The EN (Enable) pin is used to enable or disable the device. When the EN pin is high, the device is enabled, and when it is low, the device is disabled. This pin can be used to implement power-saving modes or to shut down the device during fault conditions.
  • The output voltage of the UCC2803D can be adjusted by changing the ratio of the resistors connected to the FB (Feedback) pin. The output voltage is determined by the equation: Vout = 2.5V x (R1/R2 + 1), where R1 and R2 are the resistors connected to the FB pin.
  • The maximum input voltage of the UCC2803D is 18V, but it is recommended to operate the device with an input voltage of 15V or less to ensure reliable operation.
