UC3825BN Frequently Asked Questions (FAQs)

  • The recommended input voltage range for the UC3825BN is 8.5V to 35V, although it can operate up to 40V with reduced performance.
  • To ensure stable operation, ensure that the input voltage is within the recommended range, decouple the input and output with suitable capacitors, and provide a stable clock signal.
  • The UC3825BN can deliver up to 5A of output current, but this may vary depending on the input voltage, output voltage, and thermal conditions.
  • The output voltage of the UC3825BN can be adjusted by using a resistive divider network between the output and the feedback pin (FB). The ratio of the resistors determines the output voltage.
  • The soft-start pin (SS) allows the output voltage to ramp up slowly during startup, reducing inrush currents and preventing output voltage overshoot.
