Demonstration circuit 1731A-A is a DC/DC converter demo board using the LTC3646 monolithic synchronous buck regulator in the DFN package. The input voltage range is from 4V to 40V. The output voltage range of LTC3646 is 2V to 30V. It can deliver up to 1A of output current. At light load conditions, DC1731A can operate in Burst Mode® operation to improve the efficiency. The user can choose to use internal or external compensation. The switching frequency of LTC3646 is programmable from 200kHz to 3MHz. It can be synchronized to an external clock through the MODE/SYNC pin.
