The SCT2462 is 6A synonous buck converters with wide input voltage, ranging from 3.5V to 40V, which integrates a 30mΩ high-side MOSFET a 18mΩlow-side MOSFET. The SCT2462, adopting the peak current mode control, supports the Pulse Skipping Modulation (PSM) with typical 13uA (VBIAS=5V) low quiescent current which assists the converter on achieving high efficiency at light load or stby condition.The SCT2462 features adjustable switching frequency from 200 kHz to 2.2 MHz with an external resistor,which provides the flexibility to optimize either efficiency or external component size. The converter supports external clock synonization with a frequency b from 200kHz to 2.2MHz. The SCT2462 allows power conversion from high in putvoltage to low output voltage with a minimum 60ns ontime of high-side MOSFET.The SCT2462 is an Electromagnetic Interference(EMI) friendly buck converter with implementing optimized design for EMI reduction. The SCT2462 features Frequency Spread Spectrum FSS with ±6% jittering span of the 500kHz switching frequency modulation rate 1/512 of switching frequency to reduce the conducted EMI.The SCT2462 offers cycle-by-cycle current limit hiccup over current protection, thermal shutdown protection, output over-voltage protection input voltage under-voltage protection. The device is available in 3.5mm*4mm QFN-14L package.
