LTC1628CG-SYNC#PBF datasheet by Linear Technology

LTC1628CG-SYNC#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LTC1628 can handle?
  The maximum input voltage that the LTC1628 can handle is 36V, but it's recommended to operate it within the 3.5V to 36V range for optimal performance.
• How do I ensure the LTC1628 is in sync mode?
  To ensure the LTC1628 is in sync mode, connect the SYNC pin to a clock signal that is within the specified frequency range (100 kHz to 400 kHz). The SYNC pin should be driven with a low-impedance clock source, and the clock signal should have a duty cycle between 40% and 60%.
• 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 user to turn the converter on and off. To use it, simply tie the RUN pin to VIN to enable the converter, or tie it to GND to disable it.
• How do I choose the right 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 (e.g., 10uH for the LTC1628). You can also use the inductor selection guide provided by Linear Technology or consult with an applications engineer for more specific guidance.
• What is the maximum output current that the LTC1628 can deliver?
  The maximum output current that the LTC1628 can deliver is 2A, but it's recommended to operate it within the 1A to 2A range for optimal performance and thermal considerations.
