一.产品概述


     CXSU63101是一款具有固定工作频率并且内置PFM功能的电流模式控制的的同步降压转换芯片。该芯片轻载时候进入PFM工作模式,此时工作电流只有130uA,而当它关机时只消耗1uA。

                 CXSU63101具有极低的纹波(<10mV,测试条件:5V输入,1.8V 1.2A输出,2.2uH  10uF);极好的负载调整率。这个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,CXSU63101具有从0.6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 CXSU63101 is a current mode synchronous step-down converter with fixed operating frequency. The supply current is only 130uA at operating and less than 1uA at shutdown. This device is the ideally solution for Li-Ion battery powered system applications and small size board applications. This device has internal switch, no external diode. It has internal fixed 1.5MHz frequency and makes application circuit smaller. It can reach very ripple with small capacity & inductor.

     The CXSU63101 is available in an adjustable output voltage version. The adjustable version has wide output range from 0.6V to VIN. The CXSU63101 series products are available in a low profile (1mm) tiny SOT23-5 package
