LTC3803ES6-5#TRMPBF datasheet by Linear Technology

LTC3803ES6-5#TRMPBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LTC3803 can handle?
  The maximum input voltage that the LTC3803 can handle is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
• How do I choose the right inductor value for my application?
  The inductor value depends on the output voltage, input voltage, and switching frequency. A good starting point is to use the inductor value recommended in the datasheet, and then adjust based on the specific application requirements.
• What is the purpose of the SYNC pin, and how do I use it?
  The SYNC pin allows the user to synchronize the switching frequency of the LTC3803 with an external clock signal. This can be useful in noise-sensitive applications or when multiple converters need to be synchronized.
• How do I compensate for the voltage drop across the catch diode?
  The voltage drop across the catch diode can be compensated for by adding a small voltage source (e.g., a diode-connected transistor) in series with the output voltage, or by adjusting the output voltage setting accordingly.
• What is the maximum output current that the LTC3803 can deliver?
  The maximum output current that the LTC3803 can deliver is 3A, but this depends on the input voltage, output voltage, and thermal conditions. Be sure to check the datasheet for specific current ratings and thermal derating.
