SY8502 Datasheet | Silergy

Description SY8502 develops high efficiency synchronous stepdown DC-DC converter capable of delivering 1.2A continuous, 1.8A peak current. The SY8502 operates over a wide input voltage range from 7V to 85V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. The device adopts the instant PWM architecture to achieve fast transient responses for high step down applications.
