General Description
The MAX77291 is a low-quiescent-current boost (step-up)
DC-DC converter with a 100mA peak inductor current limit
and True Shutdown™. True Shutdown disconnects the
output from the input with no forward or reverse current.
The output voltage is set with an external resistor-divider.
The output voltage can be widely varied between 5.5V and
20V.
The MAX77291 is available in a 6-bump, 0.4mm pitch,
wafer-level package (WLP).
