一.产品概述
CXSD6223是一颗耐压高至24V，输出电流1.2A的异步降压转换器，开关频率达1.4MHz，可以保证输出纹波很小，可用于对纹波要求很高的摄像模组领域。CXSD6223采用PWM/PFM自动切换的轻载高效模式，本身采用小体积的SOT23-6封装，可以节省客户的PCB占板面积。
The CXSD6223 is a wide input range, high-efficiency, high frequency DC-to-DC step-down switching regulator, capable of delivering up to 1.2A of output current. With a fixed switching frequencyof 1.4MHz, this current mode PWM controlled converter allows the use of small external components, such as ceramic input and output caps, as well as small inductors, while still providing low output ripples. Together with the tiny package CXSD6223 is in, without external compensation components, it is an ideal solution for system designer with stringentboard space requirements. CXSD6223 also employs a proprietary control scheme that switches the device into a power save mode during light load, thereby extending the range of high efficiency operation. CXSD6223 is available SOT23-6 Packages.
