UC2843BN Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the UC2843BN is 12V to 35V, with a maximum voltage rating of 40V.
  • To ensure stable operation, ensure that the input voltage is within the recommended range, decouple the power supply with a 10uF capacitor, and use a minimum of 100nF capacitor on the Vcc pin.
  • The UC2843BN can handle a maximum output current of 1A, but it's recommended to derate the current to 0.5A for reliable operation.
  • Choose an inductor value based on the output voltage, output current, and switching frequency. A general rule of thumb is to use an inductor with a value between 10uH to 100uH.
  • The bootstrap capacitor is used to generate the high-side gate drive voltage for the power MOSFET. It's typically a 10nF to 100nF capacitor connected between the Vcc and Bootstrap pins.
