DESCRIPTION
The device is dc-dc monolithic regulator specifically designed to provide extremely high efficiency. The device has on UVLO set at 2.7V cause it is part icurarly thought for single Li-ion cell applications.
Output voltage can be selected by an external divider down to 0.6V. Duty Cycle can saturate to 100% allowing low drop-out operation.
