The SCT2230H is a fully integrated high efficiency synchronous step-down DCDC converter capable of delivering 3A current. The devices operate over a wide input voltage range from 4.2V to 17V and fully integrate high-side power MOSFETs and synchronous MOSFETs with very low Rdson to

minimize the conduction loss. With 1.2MHz switching frequency, low output voltage ripple, small external inductor and capacitor size are achieved. SCT2230H adopts adaptive constant ONtime control architecture to achieve fast load transient responses for step-down applications. The SCT2230H 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, and thermal shutdown. The SCT2230H requires a minimal number of external components and is available in a spacesaving SOT563 package.
