Demonstration circuit 1778A is a single-output, synchronous buck converter featuring the LTC3883EUH, a single-output current mode controller with digital power management and input current sense capability. The DC1778A-A senses output inductor current across a sense resistor. It can be populated with the LTC3883EUH-1, which allows the user to provide bias power to the IC from an external power supply to save on-board LDO power loss.
The output voltage of the board can be programmed from 0.5V to 5V, with output current up to 20A. The factory default setting for the output is 1.8V. The DC1778A powers up to default settings and produces
