UC1825AL Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the UC1825AL is 15V to 30V, with a maximum voltage rating of 35V.
  • To ensure proper biasing, connect a 1kΩ to 2kΩ resistor between the VCC pin and the VIN pin, and a 10kΩ to 20kΩ resistor between the VCC pin and the GND 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 soft-start time.
  • The output voltage of the UC1825AL can be adjusted by connecting a resistor divider network between the output pin (VOUT) and the ground pin (GND), with the center tap connected to the feedback pin (FB).
  • The maximum output current capability of the UC1825AL is 5A, but it can be limited by the external components and the thermal design of the application.
