2A, 23V, 380KHz Step-Down Converter
FP6185
General Description
The FP6185 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 reduces the
stress on the input source during power-on. The regulator only consumes 23μA supply current in
shutdown mode. The FP6185 requires a minimum number of readily available external components to
complete a 2A buck regulator solution.
