LT3798IMSE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that the LT3798 can handle is 100V, but it's recommended to operate it within the specified input voltage range of 4.5V to 60V for optimal performance and reliability.
  • To minimize EMI, it's essential to follow good PCB layout practices, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the high-current paths. Additionally, using a shielded inductor and placing the IC away from noise-sensitive components can help reduce EMI.
  • The recommended operating frequency range for the LT3798 is 100kHz to 500kHz. Operating the IC outside of this range may affect its performance and efficiency.
  • To select the right inductor for the LT3798, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to choose an inductor with a saturation current rating of at least 1.5 times the maximum output current, and a DC resistance that is as low as possible. The core material should be suitable for the operating frequency range.
  • The maximum output current that the LT3798 can deliver depends on the input voltage and the output voltage. The IC can deliver up to 10A of output current with an input voltage of 12V and an output voltage of 5V. However, the actual output current capability may be limited by the thermal performance of the IC and the PCB.
