LTC3400-1 Datasheet (Linear) - 1.2MHz Micropower Synchronous Boost Converter

LTC3400-1, 1.2MHz Micropower Synchronous Boost Converter

of the three distinct operating modes follow.

Operation can be best understood by referring to the Block Diagram.

Low Voltage Start-Up The LTC3400-1 will start up at a typical VIN voltage of 0.85V or higher.

The low voltage start-up circuitry controls the internal NMOS switch up to a maximum peak i
