AX3821 600KHz Synchronous Rectified Step-Down Converter

The AX3821 is a monolithic synchronous buck regulator. The device integrates two 100mΩ MOSFETs, and provides 1.6A of continuous load current over a wide input voltage of 4.5V to 13V. Current mode control provides fast transient response and cycle-by-Cycle current limit. Internal soft-start prevents .
