LT3973EMSE#PBF datasheet by Linear Technology

LT3973EMSE#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LT3973 can handle?
  The LT3973 can handle input voltages up to 60V, but it's recommended to keep it below 50V for optimal performance and reliability.
• How do I optimize the layout for the LT3973 to minimize EMI and noise?
  To minimize EMI and noise, keep the input and output capacitors close to the IC, use a solid ground plane, and keep the high-current paths short and wide. Also, avoid routing sensitive signals near the inductor.
• What is the recommended inductor value and type for the LT3973?
  The recommended inductor value is between 1.5uH to 3.3uH, and a shielded inductor with a low DCR (e.g., 0.5 ohms or less) is recommended for optimal performance.
• How do I adjust the output voltage of the LT3973?
  The output voltage can be adjusted by changing the resistor divider ratio between the FB pin and the output voltage. A higher resistor value will increase the output voltage, while a lower value will decrease it.
• What is the maximum output current that the LT3973 can deliver?
  The LT3973 can deliver up to 3A of output current, but it's recommended to keep it below 2.5A for optimal performance and reliability.
