LTC3729LEUH-6#PBF Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the VIN pin is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.

  • To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the output voltage is within the recommended range of 0.8V to 5.5V.

  • The maximum current that can be drawn from the output is 2A, but it's recommended to keep it below 1.5A for optimal performance and reliability.

  • The switching frequency can be configured by selecting the appropriate value for the RT pin resistor. A higher value resistor will result in a lower switching frequency, and vice versa. The recommended range is 200kHz to 400kHz.

  • The SYNC pin is used to synchronize the switching frequency of multiple LTC3729 devices. It can also be used to synchronize the switching frequency with an external clock signal.
