AX3803 - 500KHz Synchronous Rectified Step-Down Converter

The AX3803 is a monolithic synchronous buck regulator. The device integrates two 110mΩ MOSFETs, and provides 3A of continuous load current over a wide input voltage of 4.75V to 23V. Current mode control provides fast transient response and cycle-by-Cycle current limit. Internal soft-start prevents i.
