LTC3113EFE#TRPBF datasheet by Linear Technology

LTC3113EFE#TRPBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LTC3113EFE?
  The maximum input voltage that can be applied to the LTC3113EFE is 40V, but it's recommended to keep it below 36V for reliable operation.
• How do I optimize the inductor selection for the LTC3113EFE?
  To optimize the inductor selection, consider the inductor's saturation current, DC resistance, and core loss. A good starting point is to choose an inductor with a saturation current at least 1.5 times the peak current, and a DC resistance less than 100mΩ.
• What is the recommended PCB layout for the LTC3113EFE to minimize EMI and noise?
  To minimize EMI and noise, keep the switching node (SW pin) away from sensitive analog nodes, use a solid ground plane, and place the input and output capacitors close to the IC. Also, use a shielded inductor and orient it to minimize radiation.
• How do I configure the LTC3113EFE for a specific output voltage?
  To configure the LTC3113EFE for a specific output voltage, use the VOUT pin and an external resistor divider network to set the output voltage. The output voltage can be calculated using the formula: VOUT = 0.8V x (R1 + R2) / R2.
• What is the maximum output current that the LTC3113EFE can deliver?
  The maximum output current that the LTC3113EFE can deliver is 3A, but it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
