  • The device is a DC-DC monolithic regulator specifically designed to provide high efficiency. The L6926 supply voltage can be as low as 2 V to be used 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 100% allowing low-dropout operation. The device is based on a 600 kHz fixed frequency, current mode architecture. Low consumption mode operation can be selected at light load conditions, allowing switching losses to be reduced. The L6926 is externally synchronized by a clock, which makes it useful in noise sensitive applications. Other features like Power Good, overvoltage protection, short-circuit protection and thermal shutdown (150 °C) are also present.
