In summary, the LTC3375 from Linear Technology features eight independent 1A channels with I²C control, flexible sequencing and fault monitoring in a compact QFN package. Each channel is a high efficiency synchronous step-down regulator with its own independent 2.25V to 5.5V input supply and an output voltage range of 0.425V to V_IN. The LTC3375's buck DC/DCs may be connected in parallel to achieve higher output currents up to 4A per output with a single shared inductor. Up to four adjacent regulators can be combined, resulting in fifteen different possible output configurations. All of the switching regulators are internally compensated and need only external feedback resistors to set the default output voltage. Linear Technology's LTC3375 octal, programmable, parallelable 1A buck DC/DC converter is a highly-integrated general-purpose power management solution for systems requiring multiple low voltage power supplies.
