3A, 23V, 385KHz Step-Down Converter FP6189 General Description The FP6189 is a buck regulator with a built-in internal power MOSFET. It can provide 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. Adjustable soft-start reduces the stress on the input source during power-on. The regulator only consumes 20μA supply current in shutdown mode. The FP6189 requires a minimum number of readily available external components to complete a 3A buck regulator solution. Features  3A Output Current  Adjustable Soft-Start  0.
