External Power Switch Buck Controllers

Linear Technology manufactures a broad range of step-down (buck) controllers for virtually any application. These controllers offer wide input voltage ranges, multiple output capability, multiphase operation and output tracking. Furthermore, they come in voltage-mode and current-mode topologies, offer easy synchronization to external clocks and have comprehensive protection features.
