The SCT2432 is a fully integrated synonous step-down converter supporting up to 3.5A continuous output current. The wide input voltage, ranging from 3.8V to 40V. The device offers adjustable switching frequency ranging from 300kHz to 2.2MHz, which provides flexibility to optimize efficiency, or reduce external component size, according to application requirements. It can be synonized to external clock with frequency ranging from 300kHz to 2.2MHz. The device features programmable soft start time. The SCT2432 adopts peak current mode control seamless transitions between Pulse Width Modulation (PWM) Pulse Skipping Mode (PSM), which ensures superior transient response. The quiescent current is 25μA in sleep-mode, supporting applications requiring high efficiency at light load. The SCT2432 allows power conversion from high input voltage to low output voltage with a minimum 100ns on-time of high-side MOSFET. It also supports LDO mode with low dropout from input to output. The SCT2432 is a EMI friendly device featuring with Frequency Spread Spectrum (FSS). This is an EMI friendly device featuring with Frequency Spread Spectrum (FSS). The device has built-in protections including cycle-by-cycle current limit, hiccup protection at over current, thermal shutdown protection, output over-voltage protection input voltage under-voltage protection. The SCT2432 is available in an 8-pin thermally enhanced SOP-8 package.
