目录7.相关产品 产品概述 返回TOP CXLD64206系列是把两个大电流高速LDO电压调整器芯片搭载在一起而形成的多芯片模组IC 。使用超小型表面实装封装(USP-12B01)实现了节省空间。CXLD64206系列是实现了高精度,低噪声,低压差的CMOS工艺正电压,大电流LDO电压调整器IC。内部有基准电压源,误差放大器,驱动晶体管,限流电路,相位补偿电路等构成。内置低导通电阻晶体管使得在输入输出电压差变得更小的状态下也能扩大电池的使用范围,实现了延长电池寿命。此外稳定输出的电容(CL)能使用陶瓷电容等低ESR的电容。激光微调能以0.05V的间隔内部设定0.8V~5.0V范围的输出电压。定电流限制电路和限流电路(foldback电路)能限制输出电流和保护输出端。CE功能可停止输出成待机状态。在待机模式能大幅度降低消耗电流。The CXLD64206A series is a high current, dual LDO regulator in an ultra small USP-12B01 package which measures just 2.8mm x 2.3mm. The IC is basically two XC6210 high speed CMOS LDOs which are precise, low noise, high current, regulators consisting of a voltage reference, an error amplifier, a current limiter and phase compensation circuit plus a driver transistor. The low ON resistance of the built-in driver transistor means that batteries can be used to a minimal input-output voltage differential and can therefore be used for a longer time. The series can be used with low ESR ceramic capacitors and output voltages are selectable in 0.05V increments within a range of 0.8V to 5.0V per channel. The fold-back current limit circuit also operates as the output current limiter and the output pin protector. The IC can be placed in stand-by mode via the CE function so that power consumption is greatly reduced. 产品特点 返回TOP
