BU33SD5WG-TR Frequently Asked Questions (FAQs)

  • A thermal pad is recommended under the IC to improve heat dissipation. A minimum of 2oz copper thickness and a thermal relief pattern are also recommended.
  • Ensure that the input voltage is within the recommended range, and that the output capacitor is of sufficient value and type (e.g. X5R or X7R) to maintain stability.
  • The maximum allowable ripple voltage is 1Vp-p, but it's recommended to keep it below 0.5Vp-p to ensure stable operation.
  • While ceramic capacitors can be used, they may not provide sufficient capacitance and may cause oscillation. It's recommended to use a tantalum or electrolytic capacitor instead.
  • Use the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
