The SCT2A23 is 1.2A Step-down DCDC converter with wide input voltage, ranging from 4.5V to 100V,which integrates an 530mΩ high-side MOSFET a 220mΩ low-side MOSFET. The SCT2A23, adopting the constant-on time (COT) mode control, supports the PFM mode with typical 160uA low quiescent current which assists the converter on achieving high efficiency at light load or stby condition.The SCT2A23 features able operation mode at light load, which provides the flexibility to Pulse Frequency Modulation (PFM) to achieve high efficiency at the light-load, Ultrasonic Mode (USM) to keep the switching frequency above audible frequency areas during light-load conditions, forced Pulse Width Modulation (FPWM) to achieve smaller output ripple support isolation buck topology.The SCT2A23 offers cycle-by-cycle current limit protection, thermal shutdown protection, output overvoltage protection over temperature protection.The device is available in an 8-pin thermally enhanced ESOP-8 package.
