UC2823ADW Frequently Asked Questions (FAQs)

  • The UC2823ADW requires careful layout and placement to ensure proper operation. TI recommends placing the IC close to the power supply, using a solid ground plane, and keeping the input and output traces short and separate to minimize noise and EMI.
  • The output inductor should be chosen based on the desired output voltage, current, and switching frequency. A good starting point is to use an inductor with a value between 10uH to 22uH, and a current rating that exceeds the maximum output current. TI also provides an inductor selection guide in the datasheet.
  • The UC2823ADW can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and to prevent damage to the IC.
  • The output voltage of the UC2823ADW can be adjusted by changing the ratio of the resistors in the feedback network. TI provides a formula in the datasheet to calculate the required resistor values for a specific output voltage.
  • The EN (enable) pin is used to turn the converter on and off. When the EN pin is high, the converter is enabled, and when it's low, the converter is disabled. This pin can be used to implement power sequencing or to turn off the converter during shutdown or standby modes.
