Description

The device is dc-dc monolithic regulator specifically designed to provide extremely high efficiency.

L6926 supply voltage can be as low as 2V allowing its use in single Li-ion cell supplied 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.
