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).
