FP6188概述：2A,340Khz,23V，SOP-8同步降压IC
The FP6188 is a synchronous buck regulator with integrated two 0.13 power MOSFETs. FP6188achieves 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 FP6188 includes cycle-by-cycle current limiting and thermal shutdown protection. The regulator only consumes 1uA supply current in shutdown mode. The FP6188 requires a minimum number of readily available external components to complete a 2A buck regulator solution
