SG-Micro SGM64200 | Demoboard SGM4200

Description

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.
