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).
