External Power Switch Buck-Boost
Linear Technology offers true buck-boost synchronous DC/DC converters. With their unique internal four MOSFET 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.
