SY21019 - 300mA Asynchronous Buck Converter
The SY21019 high-efficiency asynchronous Buck converter can deliver 300mA output current over a wide input voltage range from 5V to 40V.
The SY21019 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
