The SCT24A0 is 10A synchronous buck converters with wide input voltage, ranging from 3.5V to 36V, which integrates a 21mΩ high-side MOSFET and a 13mΩ low-side MOSFET. The SCT24A0, adopting the peak current mode control, supports the Pulse Skipping Modulation (PSM) with typical 0.8uA (BIAS=5V) low quiescent current which assists the converter on achieving high efficiency at light load or standby condition. The SCT24A0 features adjustable switching frequency from 200kHz to 2.2MHz with an external resistor, which provides the flexibility to optimize either efficiency or external component size. The converter supports external clock synchronization with a frequency band from 200kHz to 2.2MHz. The SCT24A0 integrates LDO function and minimum on time function, so it can support normal operation within a wide range of duty cycles. The SCT24A0 is an Electromagnetic Interference (EMI) friendly buck converter with implementing optimized design for EMI reduction. The SCT24A0 features Frequency Spread Spectrum FSS use a pseudorandom frequency hopping with ±4% jittering span of the switching frequency to reduce the conducted EMI. The SCT24A0 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 4mm*4mm FCQFN-24L package with wettable flanks.
