FP6193
3A, 23V, 340KHz Synchronous Step-Down Converter
General Description
The FP6193 is a synchronous buck regulator with integrated two 85m
Ω
power MOSFETs. It
achieves 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. The FP6193 requires
a minimum number of readily available external components to complete a 3A buck regulator solution.
