General Description |

Download | |
|
The FP6189 is a buck regulator with a built in internal power MOSFET. lt 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. Adjustable soft-start reduced the stress on the input source at 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. |
