External Power Switch Buck-Boost Controllers

Analog Devices' buck/boost synchronous dc-to-dc controllers utilize an external power switch to deliver high currents with excellent efficiency. With their unique external four MOSFET buck-boost switch combination, they can seamlessly transition from step-down mode, through 100% dropout operation, and then to step-up mode to allow a fixed output voltage even when the input voltage fluctuates above or below the output. They are particularly well suited to automotive applications where the input voltage can vary dramatically during stop/start, cold crank and load dump scenarios.
