DC1755A - Schematic3/12/2012
Demonstration circuit DC1755A provides the user with two high current dual phase synchronous buck converters driven by the LTC3860. These buck converters provide outputs of 1.5V/50A and 1.2V/50A over an input voltage range of 6V to 14V and a switching frequency of 500kHz. The board can be easily modified for a 4-phase, single VO, 100A supply. The power stage for each phase consists of the tri-state PWM compatible 6mm × 6mm Fairchild DrMOS module and a 0.47μH 13.2mm × 12.8mm iron powder type inductor from Würth. A high density, two sided drop-in layout is used. The entire converter, excluding the bulk output and input capacitors, fits within a 2.25” × 1.38” area on the board.
