Demonstration circuit 898 is a high current density supply featuring the dual-output, 2-phase synchronous buck regulator LTC3728L. The input voltage of the demo board is designed from 4.5V to 13.2V, though the LTC3728L controller can take up to 30V (max) VIN. There are two assemblies of the demo board, DC898A-A and DC898A-B. DC898A-A is a cost effective design with 2.0V/10A and 1.8V/10A outputs. DC898A-B is a high current design with 1.5V/15A and 1.2V/15A outputs.
