SY8031
High Efficiency 2.25MHz, 1.2A Synchronous Step Down Regulator
Preliminary Design Spec
General Description
The SY8031 is a high-efficiency 2.25MHz synchronous step-down DC-DC converter capable of delivering 1.2A output current. SY8031 operates over a wide input voltage range from 2.5V to 5.5V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
