产品概述 返回TOP
CXSD62526 develops high efficiency synchronous step-down DC-DC converter capable of delivering 1.2A continuous, 1.8A peak current. The CXSD62526 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.
