LT3663IMS8E-5#PBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LT3663 involves keeping the input and output capacitors close to the device, using wide traces for power lines, and separating analog and digital grounds. A 4-layer board with a solid ground plane is recommended. Refer to the LT3663 demo board layout for a reference design.
  • To ensure stability, make sure to follow the recommended component values and layout guidelines. Also, check that the output capacitor has a low ESR and is properly decoupled from the output voltage. Additionally, ensure that the input voltage is within the recommended range and that the device is not operated in a high-temperature environment.
  • The maximum input voltage for the LT3663 is 28V, but it's recommended to operate the device within the recommended input voltage range of 3.5V to 25V for optimal performance and reliability.
  • The LT3663 is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's recommended to derate the output current and ensure proper thermal management to prevent overheating.
  • The output voltage of the LT3663 can be programmed using an external resistor divider network connected to the FB pin. The resistor values can be calculated using the formula provided in the datasheet.
