LTC7815HUHF#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC7815HUHF is 60V, but it's recommended to keep it below 50V for reliable operation.
  • To select the right inductor, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to use an inductor with a saturation current of at least 2x the maximum output current and a DC resistance of less than 100mΩ.
  • The minimum input capacitance required for the LTC7815HUHF is 10uF, but it's recommended to use a higher value (e.g., 22uF) to ensure stable operation and reduce input voltage ripple.
  • The LTC7815HUHF is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
  • To minimize EMI and noise, follow good PCB layout practices such as keeping the input and output capacitors close to the IC, using a solid ground plane, and separating the high-frequency switching nodes from sensitive analog nodes.
