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.
