The SCT2434D is 3A synchronous buck converters with wide input voltage, ranging from 3.6V to 36V, Which integrates a 60mΩ high-side MOSFET and a 36mΩ low-side MOSFET. The SCT2434D, adopting the peak current mode control, supports the Pulse Skipping Modulation (PSM) with typical 30uA low quiescent current which assists the converter on achieving high efficiency at light load or standby condition. The SCT2434D features an internal 4ms soft-start time to avoid large inrush current and output voltage overshoot during startup. The switching frequency can be set between 200kHz and 2.1MHz through a resistor. The SCT2434D allows power conversion from high input voltage to low output voltage with a minimum 60ns on-time of high-side MOSFET. The SCT2434D is an Electromagnetic Interference (EMI) friendly buck converter with implementing optimized design for EMI reduction. The SCT2434D features Frequency Spread Spectrum FSS with ±10% jittering span of the switching frequency and modulation rate 1/512 of switching frequency to reduce the conducted EMI. The SCT2434D offers cycle-by-cycle current limit and hiccup over current protection, thermal shutdown protection, output over-voltage protection and input voltage under-voltage protection. The device is available in 2mm*3mm QFN-12L package with wettable flanks.
