LTC3622IDE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3622IDE is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • To minimize EMI and noise, it's recommended to follow a star-ground configuration, keep the input and output capacitors close to the IC, and use a solid ground plane. Additionally, use a shielded inductor and keep the switching node (SW) away from sensitive analog nodes.
  • The recommended output capacitor value is 10uF to 22uF, and it's recommended to use a low-ESR ceramic capacitor (X5R or X7R dielectric) to minimize output voltage ripple and ensure stability.
  • The output voltage of the LTC3622IDE can be adjusted by using a resistive divider network between the output voltage and the FB pin. The recommended resistors are 1% tolerance, and the ratio of the resistors determines the output voltage.
  • The maximum ambient temperature range for the LTC3622IDE is -40°C to 125°C, but the device can operate up to 150°C with derating. It's recommended to keep the junction temperature below 125°C for optimal performance and reliability.
