FP6188-2A,23V,340KHz Synchronous Step-Down DC


FP6188 2A, 23V, 340KHz Synchronous Step-Down Converter
General Description
Download
The FP6188 is a synchronous buck regulator with integrated two 0.13 power MOSFETs. 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 1A supply current in shutdown mode. The FP6188 requires a minimum number of readily available external components to complete a 2A buck regulator solution
