DC1807A-B - LTC3869EUFD Demo Board | VIN = 4.5V to 14V, VOUT1 = 1.5V @15A, VOUT2 = 1.2V @ 15A, with DCR Sense
Demonstration circuit 1807A is a dual output, dual phase synchronous buck converter featuring the LTC3869EUFD. The input voltage range is 4.5V to 14V, output voltages and currents are 1.5V/15A and 1.2V/15A. Two versions of the board are available. DC1807A-A has an on-board sense resistor for current feedback, while the DC1807A-B is configured with a DCR sense circuit that allows the converter to use the inductors DCR as the sense element instead of the on-board sense resistors to save cost and board space and improves efficiency.
