witcher, linear regulator and a dedicated comparator circuitry. The switcher is suitable for building output voltage up to 16 V (adjustable by resistor divider on FB pin) protected against short−circuit. Dedicated internal circuitry prevents continuous conduction mode (CCM) operation improves the surge robustness, efficiency and EMI. In no−load/light−load conditions, the part enters skip cycle operation and ensures low standby power consumption. A proprietary technique ensures high efficiency in the down−conversion process from output switcher voltage rail to raw sub voltage rail supplying a linear regulator.
