一.产品概述Jxj嘉泰姆

  The CXSD6249 is a high efficiency current mode synchronous buck PWM DC-DC regulator. The internal generated 0.8V 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 CXSD6249 is packaged in SOP-8L to reduce PCB space.Jxj嘉泰姆
