FP6189  3A, 23V ,380KHz Step-Down Converter 2020年10月停产 General Description Download     The FP6189 is a buck regulator with a built in internal power MOSFET. lt 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. Adjustable soft-start reduced the stress on the input source at power-on. The regulator only consumes 20μA supply current in shutdown mode. The FP6189 requires a minimum number of readily available external components to complete a 3A buck regulator solution. ˙Data Sheet Features ˙3A Output Current ˙Adjustable Soft-Start  ˙0.1Ω lnternal Power MOSFET Switch ˙Stable with Low ESR Output Ceramic Capacitors ˙Up to 95% Efficiency ˙20μA Shutdown Mode Current ˙Fixed 380KHz frequency ˙Thermal Shutdown ˙Cycle-by-Cycle Over Current Protection ˙Wide 4.75 to 23V operating lnput Range ˙Output Adjustable From 0.92 to 21V ˙Available SOP8 Exposed PAD ˙Under Voltage Lockout
