LTC3776EGN#PBF datasheet by Linear Technology

LTC3776EGN#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LTC3776?
  The maximum input voltage that can be applied to the LTC3776 is 60V, but it's recommended to keep it below 50V for reliable operation.
• How do I optimize the layout for the LTC3776 to minimize EMI?
  To minimize EMI, it's recommended to keep the switching node (SW pin) away from sensitive analog nodes, use a solid ground plane, and keep the input and output capacitors close to the IC. Additionally, use a shielded inductor and orient it to minimize radiation.
• What is the recommended operating frequency range for the LTC3776?
  The recommended operating frequency range for the LTC3776 is between 100kHz to 500kHz. Operating outside this range may affect efficiency and stability.
• How do I select the right inductor for the LTC3776?
  To select the right inductor, consider the maximum current rating, inductance value, and core material. A good starting point is to use an inductor with a current rating of at least 1.5 times the maximum output current, and an inductance value between 1uH to 10uH.
• What is the purpose of the SYNC pin on the LTC3776?
  The SYNC pin allows multiple LTC3776 devices to be synchronized, reducing EMI and improving system performance. It can also be used to synchronize the switching frequency with an external clock signal.
