LTC3873ETS8-5#TRPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
  • The compensation network can be optimized by following the guidelines in the datasheet and using the provided equations to calculate the values of the compensation components. Additionally, the ADIsimPower tool can be used to simulate and optimize the compensation network.
  • The minimum ESR required for the output capacitors is 10mΩ, but it's recommended to use capacitors with an ESR of 5mΩ or less for optimal performance and stability.
  • Yes, but it's not recommended. The recommended inductor value is chosen to optimize the performance and efficiency of the converter. Using a different value may affect the converter's stability and performance.
  • The switching frequency of multiple LTC3873 devices can be synchronized by connecting the SYNC pin of each device to a common clock signal. The clock signal should be within the recommended frequency range of 250kHz to 400kHz.
