LTC3721EGN-1 datasheet by Linear Technology

LTC3721EGN-1 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 28V, but it's recommended to keep it below 24V for reliable operation.
• How do I calculate the output voltage of the converter?
  The output voltage can be calculated using the formula: VOUT = 0.8V x (1 + R2/R1), where R1 and R2 are the resistors connected to the FB pin.
• What is the purpose of the RUN pin, and how do I use it?
  The RUN pin is an active-high enable input that allows the converter to be shut down or enabled. Connect it to VIN or a logic signal to enable the converter, or connect it to GND to shut it down.
• How do I choose the correct inductor value for my application?
  The inductor value depends on the input voltage, output voltage, and switching frequency. A good starting point is to use the inductor value recommended in the datasheet, and then adjust it based on the specific requirements of your application.
• What is the maximum output current that the converter can deliver?
  The maximum output current that the converter can deliver is 1.5A, but it's recommended to derate the output current based on the ambient temperature and other operating conditions.
