UC3879N Frequently Asked Questions (FAQs)

  • The recommended input capacitor value is 10uF to 22uF, with a voltage rating of 25V or higher, to ensure stable operation and minimize noise.
  • The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet, and then adjust based on the specific design requirements.
  • The UC3879N can deliver up to 2A of output current, but the actual current capability depends on the input voltage, output voltage, and thermal considerations.
  • Ensure good thermal design, including a heat sink if necessary, and follow the thermal design guidelines in the datasheet to keep the junction temperature below 125°C.
  • The EN pin is used to enable or disable the converter. Connect the EN pin to VIN to enable the converter, or connect it to GND to disable it. Use a pull-up resistor to VIN if the EN pin is not driven.
