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.
The device is based on a 600kHz fixed-frequency,
current mode-architecture. Low Consumption
Mode operation can be selected at light load
conditions, allowing switching losses to be
reduced. L6926 is externally synchronizable with
a clock which makes it useful in noise-sensitive
applications. Other features like Powergood,
Overvoltage protection, Shortcircuit protection
and Thermal Shutdown (150°C) are also present.
