The SCT2433D is 3.5A synonous buck converters with wide input voltage, ranging from 3.8V to 40V,which integrates an 80mΩ high-side MOSFET a 50mΩ low-side MOSFET. The SCT2433D, adoptingthe peak current mode control, supports Force Pulse Width Modulation (FPWM) Mode to achieve the small output ripple at light load condition.The SCT2433D features internal soft start with 570kHz switching frequency. The converter allows power conversion from high input voltage to low output voltage with a minimum 100ns on-time of high-side MOSFET. It also supports Low Drop-Out LDO operation at low voltage difference from input to output condition.The SCT2433D is an Electromagnetic Interference(EMI) friendly buck converter with implementing optimized design for EMI reduction. The SCT2433D features Frequency Spread Spectrum FSS with ±6% jittering span of the switching frequency modulation rate 1/512 of switching frequency to reduce the conducted EMI.The SCT2433D 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 an 8-pin thermally enhanced SOP-8 package.
