SY21173 Asynchronous Buck Converter

The SY21173 high-efficiency asynchronous Buck converter can deliver 3A output current over a wide input voltage range from 4.5V to 60V. The SY21173 employs a constant off-time and peakcurrent mode control strategy to achieve fast transient responses. It integrates a main switch with low RDS(ON) to m.
