2A, 23V, 1.4MHz Step-Down Converter
The FP6186 is a buck regulator with a built-in internal power MOSFET. It can provide 2A
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. This device
includes cycle-by-cycle current limiting and thermal shutdown protection. Adjustable soft-start reduces
the stress on the input source at power-on. The regulator only consumes 25μA supply current in
shutdown mode. The FP6186 requires a minimum number of readily available external components to
complete a 2A buck regulator solution.
