General Description：

The SY8308 develops a high efficiency synchronousstep-down DC/DC regulator capable of delivering 8Acontinuous current. The device integrates main switchand synchronous switch with very low RDS(ON) tominimize the conduction loss.The SY8308 operates over a wide input voltage rangefrom 4V to 40V. The device adopts the instant PWMarchitecture to achieve fast transient responses for highstep down applications and high efficiency at lightloads.
