Buck-Boost Regulators

Analog Devices offers true buck/boost synchronous dc-to-dc converters. With their unique internal four MOSFET switch combination, these switching regulators 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.
