UC3526ADW Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the UC3526ADW 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 for the oscillator circuit.
  • The UC3526ADW can deliver a maximum output current of 1.5A, but this can be limited by the external components and the application's requirements.
  • The output voltage of the UC3526ADW can be adjusted by changing the ratio of the resistors in the feedback network, or by using a potentiometer to adjust the voltage divider.
  • The soft-start pin (SS) is used to slowly ramp up the output voltage during startup, reducing inrush currents and preventing voltage overshoots.
