LM3668SD-4550EV Datasheet PDF - TI

●The LM3668 is a synchronous buck-boost DC-DC converter optimized for powering low voltage circuits from a Li-Ion battery and input voltage rails between 2.5V and 5.5V. It has the capability to support up to 1A output current over the output voltage range. The LM3668 regulates the output voltage over the complete input voltage range by automatically switching between buck or boost modes depending on the input voltage.

●The LM3668 evaluation board is a working demonstration of a synchronous buck-boost Dc-Dc converter. The application note contains information about the evaluation board. For more details and electrical characteristics about the converter operation, please refer to the datasheet.
