General Description

The MAX17270/MAX17271 are 3-output switching regulators designed for applications requiring efficient regulation of multiple supplies in a very small space, such as wearable electronic devices.

The parts use a buck-boost architecture that regulates three outputs using a single, small 2.2µH inductor at efficiencies up to 85%.

This results in smaller board space while delivering better total system efficiency than equivalent power solutions using one buck and linear regulators.
