SCT2A23A Overview
The SCT2A23A is 1.2A Step-down DCDC converter with wide input voltage, ranging from 4.5V to 100V, which integrates an 600mΩ high-side MOSFET and a 300mΩ low-side MOSFET. The SCT2A23A, 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 standby condition.
