The SCT2220 is a fully integrated high efficiencysynonous step-down DCDC converter capable ofdelivering 2A current. The devices operate over awide input voltage range from 4.2V to 17V fullyintegrate high-side power MOSFETssynonous MOSFETs with very low Rdson tominimize the conduction loss.
With 750 kHz switching frequency, low outputvoltage ripple, small external inductor capacitorsize are achieved. SCT2220 adopts adaptiveconstant ON-time control architecture to achieve fastload transient responses for step-down applications.
The devices operate in power saving mode, whichmaintains high efficiency during light load operation.It includes full protection features, such as overcurrent protection, output under-voltage protection,input under-voltage lockout, thermal shutdown.The SCT2220 requires a minimal number of externalcomponents are available in a space-savingSOT563 TSOT23 package.
