CXSD62259B是一款能够驱动5A连续负载并带有优良线性和负载调整率的同步降压型变换器。CXSD62259B的输入电压范围是8V到36V，它可工作在CC（恒流）模式下或CV（恒压）模式下。CXSD62259B可以设定为单输出或者双输出并带有独立可编程CC电流限制。CXSD62259B通过调节外部的电阻分压器提供了可编程的电缆补偿。可将COMP pin拉低至小于0.14V来实现外部关断功能。故障保护包括电流限制,短路保护和热关断。内部软启动系统能够在芯片启动过程实现小的浪涌电流和输出过冲。CXSD62259B采用的是MSOP-10的封装。The CXSD62259B is a dual-channel synchronous step-down controller capable of driving 5A continuous load with excellent line and load regulation. The CXSD62259B operates in either CC (Constant Current) mode or CV (Constant Voltage) mode with an input voltage range from 8V to 36V. The CXSD62259 can be configured as single output or dual outputs with independent programmable CC threshold for current limitation. The CXSD62259 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 CXSD62259 is available in MSOP-10 package.
