Description

L6926D is dc-dc monolithic regulator specifically designed to provide extremely high efficiency.

L6926D 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. L6926D 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. L6926D is externally synchronizable with a clock which makes it useful in noisesensitive applications. Other features like Powergood, Overvoltage protection, Shortcircuit protection and Thermal Shutdown (150°C) are also present.
