LTC7819RUJ#TRPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC7819RUJ is 40V, but it's recommended to keep it below 36V for reliable operation.
  • Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value based on the switching frequency and output voltage. A good starting point is to use an inductor with an inductance value between 1uH to 10uH.
  • The minimum ESR required for the output capacitor is 10mΩ, but it's recommended to use a capacitor with an ESR of 1mΩ or less for optimal performance.
  • Yes, a ceramic capacitor can be used for the output capacitor, but it's recommended to use a capacitor with a high ripple current rating and a low ESR to ensure reliable operation.
  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESR) / (2 * fsw * Cout), where Iout is the output current, ESR is the equivalent series resistance of the output capacitor, fsw is the switching frequency, and Cout is the output capacitance.
