Demonstration circuit 971 is a high current density supply featuring the dual-output, 2-phase synchronous buck regulator LTC3811. The input voltage of the demo board is designed from 4.5V to 14V. The outputs are 2V/15A and 1.5V/15A. The output voltages can be programmed with different start-up tracking modes. All the critical power and controller IC circuits on the DC971 board are within a 1.45 × 0.9 drop-in PCB layout space. The outputs can be easily configured to have two separated output voltages or a single high current output voltage with two phases in paralleling.
