一.产品概述
CXSU63117是一款具有固定工作频率的电流模式控制的的同步降压转换芯片。它的工作电流只有130uA，而当它关机时只消耗1uA。CXSU63117对于锂电池供电系统和小尺寸电路板的应用来说是理想的解决方案。器件具有内置的开关，因此不需要外部的续流二极管，另外还具有1.5MHZ的频率可以使外部的pcb的布局面积很小。
CXSU63117具有1.2V，1.8V，3.3V和输出可调等4种输出版本的产品。其中输出可调的产品具有从0.6V到Vin的宽范围电压输出能力。这个产品的封装是很小的SOT23-5L。
The CXSU63117 is a current mode synchronous step-down converter with fixed operating frequency. The supply current is only 20uAat operating and less than 1uA at shutdown. This device is theideally solution for Li-Ion battery powered system applications and small size board applications. This device has internal switch, noexternal diode. It has in ternal fixed 1.5MHz frequency and makes application circuit smaller. It can reach very ripple with smallcapacity & inductor.
The CXSU63117 is available in an adjustable output voltage version. The adjustable version has wide output range from 0.6V to VIN. The CXSU63117 series products are available in a low profile (1mm) tiny SOT23-5 package.
