DESCRIPTION：

 

The SCT2432C is 3A synchronous buck converters with wide input voltage, ranging from 3.8V to 40V,which integrates an 160mΩ high-side MOSFET and an 80mΩ low-side MOSFET. The SCT2432C, adopting the peak current mode control, supports the Pulse Skipping Modulation (PSM) with typical 25uA low quiescent current which assists the converter on achieving high efficiency at light load or standby condition. The SCT2432C features programmable the soft-start time together with the programmable switching frequency from 300 kHz to 1.2 MHz 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 300kHz to 1.2MHz. The SCT2432C allows power conversion from high input voltage to low output voltage with a minimum 80ns ontime of high-side MOSFET. The SCT2432C is an Electromagnetic Interference (EMI) friendly buck converter with implementing optimized design for EMI reduction. The SCT2432C features Frequency Spread Spectrum FSS with ±6% jittering span of the switching frequency and modulation rate 1/512 of switching frequency to reduce the conducted EMI. The SCT2432C 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 an 8-pin thermally enhanced SOP-8 package.
