L6928 is a high efficiency monolithic synchronous step down regulator featuring extremely low quiescent current, 2V to 5.5V input voltage range, up to 95% efficiency, as well as selectable low noise/low consumption mode.
The L6928 is a DC-DC monolithic regulator specifically designed to provide extremely high efficiency with an input voltage range from 2 V to 5.5 V. It features an internal synchronous switch, eliminating the need for external Schottky diodes, and supports adjustable output voltages down to 0.6 V. The device operates with a 1.4 MHz switching frequency and can be externally synchronized from 1 MHz to 2 MHz.
