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).
