SY26407 Datasheet | Silergy

High Efficiency, 1A, 100V Input Synchronous Step Down Regulator General Description The SY26407 develops a high efficiency synchronous step-down DC/DC converter capable of delivering 1A current. The SY26407 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 SY26407 always operates under Continuous Conduction Mode. The SY26407 adopts the instant PWM architecture to achieve fast transient responses for high step down applications.
