一.产品概述
CXSU63102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 CXSU63102/CXSU63102F synchronous buck converter is a high frequency stepdown voltage regulator with current control mode. It can output 1.5A with excellent line and load regulation. The current is only 130uA/20uA 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 CXSU63102/CXSU63102F 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 CXSU63102/CXSU63102F is available in an adjustable output voltage version. The adjustable version has wide output range from 0.6V to VIN. The CXSU63102/CXSU63102F series products are available in a DFN-6L 2X2package.
