LT8642SIV#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that the LT8642SIV#PBF can handle is 42V, but it's recommended to keep it below 36V for optimal performance and reliability.
  • To minimize EMI, keep the input and output capacitors close to the IC, use a solid ground plane, and keep the high-frequency switching nodes (e.g., LX and SW) away from sensitive analog nodes. Also, use a shielded inductor and orient it to minimize radiation.
  • A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value between 10uF to 22uF is recommended for the output capacitor. The exact value depends on the specific application requirements and output voltage ripple.
  • The switching frequency of the LT8642SIV#PBF can be adjusted by connecting a resistor (RT) between the RT pin and the GND pin. The switching frequency (fSW) is inversely proportional to RT. Consult the datasheet for the specific formula and recommended values.
  • The maximum output current that the LT8642SIV#PBF can deliver is 2A, but it's recommended to derate the output current based on the ambient temperature and the specific application requirements.
