SYVM78A Overview
The SYVM78A develops a high efficiency asynchronous step down DC/DC regulator, which is capable of delivering 0.8A output current. The IC adopts current mode adaptive constant off time control. The SYVM78A operates over a wide input voltage range from 4.5V to 55V and integrates main switch with very low RDS(ON) to minimize the conduction loss.
