SY21061 - Asynchronous Buck Converter
The SY21061 high-efficiency asynchronous Buck converter can deliver 1.2A output current over a wide input voltage range from 5V to 40V.
The SY21061 employs a constant off-time and peak current mode control strategy to achieve fast transient responses.
It integrates a main switch with low RDS(ON) to
