DESCRIPTION
The device is a DC-DC monolithic regulator specifically designed to provide high efficiency. Output voltage can be selected by an external divider down to 0.6 V. Duty cycle can saturate 100% allowing low-dropout operation. Low consumption mode operation can be selected at light load conditions, allowing switching losses to be reduced.
