L6925/6/8 are 800 mA switching regulators that implement burst mode control. Together with a very low quiescent current at zero load, burst mode produces high efficiency even at loads lower than 1 mA. Depending on the setting of the SYNC pin these parts can be set in low power (PFM) or low noise (forced PWM) modes of operation. Switching frequency can be synchronized to an external clock of up to 2 MHz.
