FP6183 2A, 23V, 210KHz Step-Down Converter General Description Download The FP6183 is a buck regulator with a built in internal power MOSFET. lt 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. Adjustable soft-start reduced the stress on the input source at power-on. The regulator only consumes 23μA supply current in shutdown mode. The FP6183 requires a minimum number of readily available external components to complete a 2A buck regulator solution. ˙Data Sheet ˙Application Note Features ˙2A Output Current ˙Adjustable Soft-Start ˙0.2Ω lnternal Power MOSFET Switch ˙Stable with Low ESR Output Ceramic Capacitors ˙Up to 95% Efficiency ˙23μA Shutdown Mode Current ˙Fixed 210KHz frequency ˙Thermal Shutdown ˙Cycle-by-Cycle Over Current Protection ˙Wide 4.75 to 23V operating lnput Range ˙Output Adjustable From 1.23 to 18V ˙Available SOP8 & PDIP8 Package ˙Under Voltage Lockout
