External Power Switch Buck Controllers

Analog Devices Inc. External Power Switch Buck Controllers are a broad range of step-down (buck) controllers for almost any application. The controllers offer wide input voltage ranges, multiple output capability, multiphase operation, and output tracking. They come in voltage-mode and current-mode topologies, offer easy synchronization to external clocks, and possess comprehensive protection features.
