UC3861N Frequently Asked Questions (FAQs)

  • The recommended input capacitor value is 10uF to 22uF, depending on the input voltage and output current requirements.
  • To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient input capacitor, and add a compensation capacitor (typically 10nF to 22nF) between the COMP and GND pins.
  • The UC3861N can deliver up to 1A of output current, but this may vary depending on the input voltage, output voltage, and thermal conditions.
  • The output voltage can be adjusted by changing the resistor divider network connected to the FB pin. The output voltage is determined by the ratio of the resistors and the internal reference voltage (2.5V).
  • The EN (Enable) pin is used to enable or disable the regulator. When the EN pin is pulled low, the regulator is disabled, and the output voltage is turned off.
