一.产品概述Rch嘉泰姆

The CXSD6240 is a high efficiency current mode synchronous buck PWM DC-DC regulator. 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 CXSD6240 is packaged in SOT23-5L, and TSOT23-5L to reduce PCB space Rch嘉泰姆
