DC2836A, Power Management IC Development Tools LT7182S Demo Board

DC2836A is a LT7182S dual channel 6A, 20V, polyphase step-down silent switcher with digital power system management demonstration board. Demonstration Circuit 2836A is a dual-output PolyPhase® DC/DC synchronous step-down regulator with 4V to 20V input range featuring LT®7182S. Each output can supply 6A continuous/9A maximum transient load current. LT7182S is a dual 6A monolithic step-down regulator. The second-generation Silent Switcher® structure is incorporated into LT7182S to minimize EMI and reduce PCB layout sensitivity. It also integrates digital power system management function allowing for programmability and telemetry with a PMBus/I2C compliant serial interface. The demonstration circuit 2836A runs at 1MHz to minimize solution size. The peak efficiency at 12V input is 83.2% for 1.2V rail and 91.1% for 3.3V rail. The IC temperature rise is 70°C when both channels run at full load, 6A each at 1MHz.

• Switching frequency of 1MHz(typ) at TA = 25°C
