一.产品概述
CXSU63103是一款具有固定工作频率的电流模式控制的同步降压转换芯片，该芯片最高可以输出1.5A的电流。它的工作电流只有130uA，而当它关机时只消耗1uA。该器件对于诸如数据卡，手机等设计空间要求高的电池供电产品来说是一个很好的解决方案。
该产品内部集成了PWM控制器，功率开关管和内部补偿网络，最少只需要5个外围器件就可以实现一个高达1.5A输出的电源。高达1.5MHz的频率可以使外围电路尺寸很小。
The CXSU63103 synchronous buck converter is a high frequency step-down voltage regulator with current control mode. It can output 1.5A with excellent line and load regulation. The current is only 130uA at operating and less than 1uA at shutdown. This device is the ideally solution for small space and battery powered consume application, such as cellular phone and Hand-held device. The CXSU63103 integrates PWM controller, power switch and compensation network, required only five components to implement a 1.5A output switching power supply. It has internal fixed 1.5MHz frequency and makes application circuit smaller.
The CXSU63103 is available in an adjustable output voltage version. The adjustable version has wide output range from 0.6V to VIN. The CXSU63103 series products are available in a DFN-10L 3X3package.
