FP6183
General Description
The FP6183 is a buck regulator with a built in internal power MOSFET. It achieves 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. 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 23µA supply current in shutdown
mode. The FP6183 requires a minimum number of readily available external components to complete
a 2A buck regulator solution.
