The SCT2230A is a fully integrated high efficiency synonous step-down DCDC converter capable of delivering 3A current. The devices operate over a wide input voltage range from 4.2V to 17V fully integrate high-side power MOSFETs synonous MOSFETs with very low Rdson to minimize the conduction loss.With 750 kHz switching frequency, low output voltage ripple, small external inductor capacitor size are achieved. SCT2230A adopts adaptive constant ONtime control architecture to achieve fast load transient responses for step-down applications.The SCT2230A operates in power saving mode,which maintains high efficiency during light load

operation.It includes full protection features, such as over current protection, output under-voltage protection,input under-voltage lockout, thermal shutdown.The SCT2230A requires a minimal number of external components is available in a spacesaving SOT563 package.
