CX8501 Datasheet | CHENGXINWEI

Description CX8501develops high efficiency synchronous stepdown DC-DC converter capable of delivering 1.0A current. The CX8501 operates over a wide input voltage range from 7V to 100V 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.
