Description
The device is DC-DC monolithic regulator specifically designed to provide extremely high efficiency.
L6926 supply voltage can be as low as 2 V allowing its use in single Li-ion cell supplied applications. Output voltage can be selected by an external divider down to 0.6 V.
Duty cycle can saturate to 100 % allowing low drop-out operation.
