LTC3617EUDD#PBF datasheet by Linear Technology

LTC3617EUDD#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LTC3617EUDD can handle?
  The maximum input voltage that the LTC3617EUDD can handle is 42V, but it's recommended to operate it within the 5.5V to 36V range for optimal performance.
• How do I optimize the layout for the LTC3617EUDD to minimize EMI?
  To minimize EMI, 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) away from sensitive nodes.
• What is the recommended inductor value and type for the LTC3617EUDD?
  The recommended inductor value is between 1.5uH to 3.3uH, and a shielded inductor is recommended to minimize EMI. The inductor type should be a low-loss, high-current inductor with a high saturation current rating.
• How do I adjust the output voltage of the LTC3617EUDD?
  The output voltage of the LTC3617EUDD can be adjusted by changing the resistor divider ratio of the feedback resistors (RFB1 and RFB2). The output voltage can be calculated using the formula: VOUT = 0.8V x (1 + RFB2/RFB1).
• What is the maximum output current that the LTC3617EUDD can deliver?
  The maximum output current that the LTC3617EUDD can deliver is 2A, but it's recommended to operate it within the 1.5A range for optimal performance and thermal considerations.
