FUNCTION
Programming pin for setting the output to any value lower than the normal fixed
voltage.
Ground.
Battery input voltage.
Boost inductor connection.
Return for the internal power transistors.
Boost inductor connection.
Pulling this pin to VIN through an external resistor shuts down the regulator,
isolating the load from the input.
Boost regulator output.
Absolute Maximum Ratings
Absolute Maximum Ratings are those values, beyond which the device could be permanently damaged. Absolute maximum
ratings are stress ratings only and functional device operation is not implied.
