SCT2A21 Datasheet (SCT) - Constant On-Time Synchronous BUCK Converter

SCT2A21, Constant On-Time Synchronous BUCK Converter

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 wh
