LTC3414EFE datasheet by Linear Technology

LTC3414EFE Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the VIN pin?
  The maximum input voltage that can be applied to the VIN pin is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the internal components.
• How do I optimize the layout for the LTC3414EFE to minimize EMI and noise?
  To minimize EMI and noise, it's recommended to follow a star-ground configuration, keep the input and output capacitors close to the IC, and use a solid ground plane. Additionally, use a shielded inductor and keep the switching node (SW pin) away from sensitive nodes.
• What is the recommended inductor value and type for the LTC3414EFE?
  The recommended inductor value is between 1uH to 10uH, and a shielded inductor with a low DCR (direct current resistance) is recommended. The inductor type should be able to handle the peak current and have a high saturation current rating.
• How do I set the output voltage of the LTC3414EFE?
  The output voltage of the LTC3414EFE can be set by using a resistive divider network between the VOUT pin and the GND pin. The ratio of the resistors determines the output voltage, and the recommended range is between 0.8V to 5V.
• What is the maximum output current that the LTC3414EFE can deliver?
  The maximum output current that the LTC3414EFE can deliver is 1.5A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
