目录7.相关产品 产品概述 返回TOP CXSB6613系列是把内置驱动晶体管的600mA同步整流器降压DC/DC转换器和对应低输入电压工作的400mA LDO电压调整器集成化的多芯片模组IC。由于使用了超小型表面实装封装(USP-12B01)实现了节省空间。此外，在封装内部DC/DC转换器和LDO调整器完全分离，把DC/DC转换器的噪声干扰对LDO电压调整器的影响抑制在最小限度。由于使用了即使在低输出电压时用低通阻抗能工作的产品，可以从DC/DC转换器的低输出电压中再实现另一个高效率低噪声的低输出电压。此外，与使用两个降压DC/DC转换器时相比，减少了一个线圈，利于减少外围元件及缩小电路板空间。The CXSB6613 series is a multi combination module IC which comprises of a 600mA driver transistor built-in synchronous step–down DC/DC converter and a low voltage input LDO regulator. The device is housed in small USP-12B01 package which is ideally suited for space conscious applications. Battery operated portable products require high efficiency so that a dual DC/DC converter is often used. The CXSB6613 can replace this dual DC/DC to eliminate one inductor and reduce output noise. The DC/DC converter and the LDO regulator blocks are isolated in the package so that noise interference from the DC/DC to the LDO regulator is minimal. A low output voltage and low On-resistance LDO regulator is added in series to the DC/DC output so that one another low output voltage is created with a high efficiency and low noise. With comparison to the dual DC/DC solution, one inductor can be eliminated which results in parts reduction and board space saving. 产品特点 返回TOP
