LTC3900IS8#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3900 is 36V, but it's recommended to keep it below 30V 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 not explicitly stated in the datasheet, but a good rule of thumb is to choose a capacitor with an ESR of less than 10mΩ to ensure stable operation.
  • The LTC3900 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation. Consult the datasheet for thermal derating curves.
  • Follow good PCB layout practices such as separating the power and signal grounds, using a solid ground plane, and keeping the switching node (SW pin) away from sensitive analog nodes. Also, use a shielded inductor and keep the input and output capacitors close to the IC.
