UC3525ANG4 Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the UC3525ANG4 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 soft-start pin (SS) is used to control the output voltage ramp-up time during power-up. It can be connected to a capacitor to ground to set the ramp-up time.
  • The output voltage of the UC3525ANG4 can be calculated using the formula: Vout = (1 + R2/R1) x Vref, where R1 and R2 are the feedback resistors, and Vref is the internal reference voltage (5V).
  • The maximum output current capability of the UC3525ANG4 is 1.5A, but it can be limited by the external components and the thermal design of the system.
