Overview
FP6180 3A, 23V, 380KHz Step-Down Converter General Description The FP6180 is a buck regulator with a built in internal power MOSFET.
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.
Adjustable soft-start reduced the stress on the input source at power-on.
The regulator only consumes 20μA supply current in shutdown mode.
The FP6180 requires a minimum number of readily available external components to complete a 3A buck regulator solution.
