产品概述 返回TOP
The CXDC6572 is a high efficiency current mode synchronous buck PWM DC-DC . The internal generated 0.6V precision feedback reference voltage is designed for low output voltage. Low RDS (ON) synchronous switch dramatically reduces conduction loss. To extend battery life for portable application, 100% duty cycle is supported for low-dropout operation. Shutdown mode also helps saving the current consumption. The CXDC6572 ( MSOP-10L) to reduce PCB space
