1 / 17 page October 2006 Rev 7 1/17 17 L6926 High efficiency monolithic synchronous step down regulator General features ■ 2V to 5.5V battery input range ■ High efficiency: up to 95% ■ Internal synchronous switch ■ No external schottky required ■ Extremely low quiescent current ■ 1mA max shutdown supply current ■ 800mA max output current ■ Adjustable output voltage from 0.6V ■ Low drop-out operation: up to 100% duty cycle ■ Selectable low noise/low consumption mode at light load ■ Power good signal ■ ±1% output voltage accuracy ■ Current-mode control ■ 600kHz switching frequency ■ Externally synchronizable from 500kHz to 1.4MHz ■ OVP ■ Short circuit protection Applications ■ Battery-powered equipments ■ Portable instruments ■ Cellular phones ■ PDAs and hand held terminals ■ DSC ■ GPS 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.
