The SGM64200 integrates two synchronous Buck controllers which can be configured as two independent single-phase outputs or one dual-phase output. Two devices can also be linked up as a master-slave through an external pin to provide four single-phase outputs or two dual-phase outputs. The switching phases of linked devices are adjustable to achieve four phases interleaving. The device accepts an input range from 3V to 20V with a precise reference voltage of 0.6V.
The controllers employ fixed frequency voltage mode PWM regulation scheme. Separated enable, current-sense and PGOOD pins are incorporated to allow soft-start times and current limits to be programmable individually. The device offers individual over-current, output over-voltage and output under-voltage protections.
