4 Application information
Note: Represents a typical application schematic for an output current of 800 mA (max) in
continuous mode operation. For pulse/flash mode operation it is possible to increase the
maximum output current up to 1 A. If the battery voltage is higher than 3.1 V, the chip is
capable of delivering the maximum output current of up to 1 A in continuos mode.
Note: The above-listed external components refer to a typical application. Operation of the
STCF07 is not limited to the use of these components.
