SY21102 Description
The SY21102 high efficiency asynchronous Buck converter can deliver 2A output current over a wide input voltage range from 5V to 40V. The SY21102 employs a constant off-time and peak current mode control strategy to achieve fast transient responses. It integrates a power MOSFET with low RDS(ON) to minimize conduction loss.
