AX3484概述：3A，23V，340KHZ同步整流降压DC-DC
The AX3484 is a synchronous buck regulator with integrated two 85mΩ power MOSFETs. It achieves 3A continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. The device includes cycle-by-cycle current limiting and thermal shutdown protection. The regulator only consumes 1A supply current in shutdown mode. The FP6193 requires a minimum number of readily available external components to complete a 3A buck regulator solution with minimal external components.
