provides an auxiliary7V output, primarily for the gate-drive supply, which canbe used for applications requiring auxiliary output, such as5 V, by linear regulating. The primary output starts up under full loadat input
voltages typicallyas lowas 0.8V witha ensured maxof1V, and operates downto 0.5V once the converteris
operating, thereby maximizing battery usage.
