The SCT2324 is a 2A synchronous buck converter with wide input voltage, ranging from 3.8V to 30V, which integrates a 90mΩ high-side MOSFET and a 36mΩ low-side MOSFET. The SCT2324, adopting the peak current mode control, supports the Pulse Skipping Modulation (PSM) which assists the converter on achieving high efficiency at light load or standby condition. The switching frequency can be programmed from 200kHz to 2.2MHz through external resistors to optimizes either the power efficiency or the external components’ sizes. The SCT2324 allows power conversion from high input voltage to low output voltage with a minimum 80ns on-time of high-side MOSFET. The SCT2324 is an Electromagnetic Interference (EMI) friendly buck converter with implementing optimized design for EMI reduction. The SCT2324 features Random Spread Spectrum ±6%

jittering span of switching frequency to reduce the conducted EMI. The device offers programmable soft start to prevent inrush current during the startup of output voltage ramping. The SCT2324 supports monotonic start with pre-biased output. The SCT2324 features internal loop compensation, which can provide stable output voltage and fast loop response, while reducing off chip configuration. The SCT2324 provides cycle-by-cycle current limit, hiccup mode for over current protection, thermal shutdown protection, output over-voltage protection and input voltage under-voltage protection. The device is available in an FCSOT583 package.
