UC3825AN Frequently Asked Questions (FAQs)

  • The recommended input voltage range for the UC3825AN 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 with a 10uF capacitor, and use a minimum of 100nF capacitor on the Vref pin.
  • The soft-start pin (SS) allows the user to control the turn-on time of the converter, reducing inrush current and electromagnetic interference (EMI).
  • The maximum output current of the UC3825AN can be calculated using the formula: Iout(max) = (Vin - Vout) / (Rds(on) * L), where Vin is the input voltage, Vout is the output voltage, Rds(on) is the on-resistance of the internal switch, and L is the inductor value.
  • The undervoltage lockout (UVLO) feature on the UC3825AN prevents the converter from operating below a certain input voltage threshold (typically 8.5V), ensuring that the converter operates within a safe and stable region.
