• Input Voltage Range 4 V to 40 V with Transient regulator’s standby current is 28 μA in ECO mode,

Up to 65 V which is suitable for battery operating systems. An

• Output Current up to 600 mA ultra-low 1 μA shutdown current can further prolong

battery life. Operating frequency is fixed at 2.1 MHz • 2.1 MHz Switching Frequency allowing the use of small external components while

• Ultra Low 28 μA Standby Current in ECO Mode still being able to have low output ripple voltage. Soft•

1 μA Shutdown Current start and compensation circuits are implemented

internally, which allows the device to be used with • High Duty Cycle Operation Supported
