This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX17220–MAX17225 is a family of ultra-low quiescent current boost (step-up) DC-DC converters with a 225mA/0.5A/1A 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 selectable using a single standard 1% resistor.
