内部电源开关 降压-升压型稳压器：linear Technology offers the Industry's only 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.（15）
