2A, 23V, 380KHz Step-Down Converter
FP6182
General Description
The FP6182 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. The regulator only consumes 25μA
supply current in shutdown mode. The FP6182 requires a minimum number of readily available
external components to complete a 2A buck regulator solution.
