Demonstration circuit DC2380A features the LTC®7851,a high performance 4-phase voltage mode controller, inthe following high output current step-down converters:DC2380A-A: 1.8V/30A, 1.5V/30A, 1.2V/30A and 1.0V/30ADC2380A-B: 1.8V/60A Dual Phase and 1.2V/60A Dual PhaseDC2380A-C: 1.2V/120A 4-PhaseThe above converters provide a maximum per phasecurrent of 30A while operating at a frequency of 400kHzover an input voltage range of 7V to 14V. The powerstage of each phase consists of a 5mm × 5mm DrMOSand 0.25μH/0.325mΩ inductors. The PWM outputs of theLTC7851 drive each DrMOS and DCR sensing is employedto sense the inductor current. The LTC7851’s integratedcurrent share circuit provides highly accurate currentsharing in the DC2380A-B and DC2380A-C converters.These demo boards use a high density, two sided layoutwhich places the power stage on the top and the controlcircuit on the bottom. The LTC7851 and DrMOS are biasedby an onboard LT3970 buck converter.Additional features of this demo board include:n Remote Sensingn CLKIN and CLKOUT Pinsn PGOOD, RUN and TRACK/SS Pinsn Dynamic Load CircuitThe LTC7851 data sheet provide a complete descriptionof the IC operation and application information. The datasheet must be read in conjunction with the quick start guide.
