SCT2A21 Overview
The SCT2A21 is a 1A synchronous buck converters with wide input voltage, ranging from 4.5V to 100V, which integrates an 530mΩ high-side MOSFET and a 220mΩ low-side MOSFET. The SCT2A21, adopting the constant-on time (COT) mode control, supports the PFM mode with typical 150uA low quiescent current which assists the converter on achieving high efficiency at light load or standby condition. Applying an external diode...
