Internal Power Switch Buck-Boost

Analog Devices offers true buck/boost synchronous dc-to-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.
