Introduction
The SCT2432Q is 3.5A synchronous buck converters with wide input voltage, ranging from 3.8V to 40V, which integrates an 80mΩ high- side MOSFET and a 50mΩ low- side MOSFET. The SCT2432Q, 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 SCT2432Q features programmable the soft- start time together with the programmable switching frequency from 300kHz 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 300kHz to 2.2MHz. The SCT2432Q allows power conversion from high input voltage to low output voltage with a minimum 100ns on- time of high- side MOSFET.
The SCT2432Q is an Electromagnetic Interference (EMI) friendly buck converter with implementing optimized design for EMI reduction. The SCT2432Q 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 SCT2432Q 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.
