The SCT2820 is 2A synchronous buck converters with wide input voltage, ranging from 4.4V to 80V, which integrates a 320mΩ high-side MOSFET and a 160mΩ low-side MOSFET. The SCT2820, adopting the peak current mode control, supports the Pulse Skipping Modulation (PSM) with typical 36uA low quiescent current which assists the converter on achieving high efficiency at light load or standby condition. The SCT2820 features an internal 3.5ms soft-start time to avoid large inrush current and output voltage overshoot during startup. The switching frequency can be adjusted from 200kHz to 1.5MHz. The SCT2820 integrates LDO function and minimum on time function, so it can support normal operation within a wide range of duty cycles. The SCT2820 is an Electromagnetic Interference (EMI) friendly buck converter with implementing optimized design for EMI reduction. The SCT2820 features Frequency Spread Spectrum FSS uses a pseudorandom frequency hopping with ±8% jittering span of the switching frequency to reduce the conducted EMI. The SCT2820 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 ESOP-8L package.
