General Description

The MAX17291C is a low quiescent current, boost (stepup),

DC-DC converter with 80mA 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 MAX17291C is available in a 6-bump, 0.4mm pitch,

wafer level package (WLP).
