   产品概述 返回TOPR5u嘉泰姆

       CXSD62264A是一款工作在CC或CV模式的降压型DC-DC变换器，可以提供高达3A的负载电流，其具有很好的线性和负载调整率。CXSD62264A可以在宽输入电压范围8V～36V内稳定工作，CXSD62264A提供了通过外部电阻分压器实现的可编程线缆补偿，而当输出电压超过额定电压时，同样通过外部电阻分压实现开关关断。CXSD62264A在故障预防与处理方面，具有二次循环峰值电流限制、短路保护以及过温关断等保护机制。芯片在关断模式下的静态电流可低至3μA以下。芯片内部软启动有效减小了输入浪涌电流和启动时的输出过冲。CXSD62264A 采用SOP-8封装。The CXSD62264A is a step-down converter capable of driving 3A continuous load with excellent line and load regulation. The CXSD62264A operates in either CC (Constant Current) mode or CV (Constant Voltage) mode with an input voltage range from 8V to 36V. The CXSD62264A provides programmable cable compensation by adjusting external resistor divider. The CXSD62264 stops switching when the output reaches over voltage threshold which is programmed by external resistor divider. Fault protection includes secondary cycle-by-cycle current limit, short circuit protection and thermal shutdown. In shutdown mode the regulator draws 3μA of supply current. Internal soft-start minimizes the inrush supply current and the output overshoot at initial startup. The CXSD62264 is available in SOP-8 package.
