SCT2A10ASTER

The SCT2A10A is 0.6A synchronous buck converters with wide input voltage, ranging from 4.5V to 100V, which integrates an 750mΩ high-side MOSFET and a 500mΩ low-side MOSFET. The SCT2A10A, adopting the constant-on time (COT) mode control, supports the PFM with typical 100uA low quiescent current which assists the converter on achieving high efficiency at light load or standby condition. The SCT2A10A features programmable switching frequency from 300kHz to 800kHz, which provides the flexibility to optimize either efficiency or external component size. The SCT2A10A 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.
