目录7.相关产品 产品概述 返回TOP CXSD62288是一款同步电流模的降压型DC-DC变换器，可以提供高达3A的负载电流，具有很好的线性和负载调整率。CXSD62288可以在宽输入电压范围4.5V～30V内稳定工作，通过外部反馈电阻可以方便实现0.925V~20V的输出电压。CXSD62288具有周期性的峰值电流限制和过温等保护功能，以确保芯片工作的可靠性。芯片关断时的静态电流可低至1μA以下。可编程的软启动功能可以有效减小输入浪涌电流和启动时的输出过冲。CXSD62288采用少量的标准外围器件即可实现变换器功能。The CXSD62288 is a synchronous current mode buck regulator capable of driving 3A continuous load current with excellent line and load regulation. The CXSD62288 can operate with an input range 4.5V to 30V and the output can be externally set from 0.925V to 20V with a resistor divider. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. In shutdown mode the regulator draws 1μA of supply current. Programmable soft-start minimizes the inrush supply current and the output overshoot at initial startup. The CXSD62288 require a minimum number of external components.产品特点 返回TOP
