UC3525BDW Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the UC3525BDW 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 Vref pin.
  • The Vref pin is used to set the internal reference voltage, which is used to regulate the output voltage. A capacitor (typically 100nF) should be connected between Vref and ground to filter the reference voltage.
  • The output voltage can be adjusted by connecting a resistive divider network between the output and ground, with the center tap connected to the Feedback (FB) pin.
  • The maximum output current capability of the UC3525BDW is 5A, but this can be limited by the external components and the thermal design of the system.
