General Description

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 minimize conduction loss.
