CXSD62260是一款同步的恒压/恒流模式的降压型DC-DC变换器，可以提供高达4A的负载电流，具有很好的线性和负载调整率。CXSD62260的恒压/恒流模式都可以在宽输入电压范围4.5V～36V内稳定工作，CXSD62260可通过外部电阻调节来实现可编程的走线电压补偿，外部关断功能可以通过把COMP引脚电压下拉到0.14v以下来实现CXSD62260具有短路保护、过温等保护机制和间接的周期性电流限制，以确保芯片工作的安全性。芯片内部的软启电路有效减小了输入浪涌电流和启动时的输出过冲CXSD62260可以用SOP-8封装。The CXSD62260 is a synchronous step-down converter capable of driving 4A continuous load with excellent line and load regulation. The CXSD62260 operates in either CC (Constant Current) mode or CV (Constant Voltage) mode with an input voltage range from 4.5V to 36V. The CXSD62260 provides programmable cable compensation by adjusting external resistor divider. External shutdown function can be controlled by pulling COMP pin to a level below 0.14V. Fault protection includes secondary cycle-by-cycle current limit, short circuit protection and thermal shutdown. Internal soft-start minimizes the inrush supply current and the output overshoot at initial startup. The CXSD62260 is available in SOP-8 (EP) package.
