The SY8521 develops a high efficiency synchronous step-down DC/DC converter capable of delivering 0.6A current. The SY8521 operates over a wide input voltage range from 7V to 100V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. The SY8521 always operates under continuous condition mode. The device adopts the instant PWM architecture to achieve fast transient responses for high step down applications.
