一.产品概述
PMU/tongbu/2019-11-01/444.html target=_blank class=infotextkey>CXSD6222是一款在SOT23-8的超小封装内实现工作电压达18V,输出电流达2A,能量转换效率达91%的高压同步降压转换器。其采用了PWM/PFM自动切换的轻载高效控制模式和内部补偿的构架。是外围引脚最为节省的高压同步降压转换器
The PMU/tongbu/2019-11-01/444.html target=_blank class=infotextkey>CXSD6222 is a wide input range, synchronous, high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 2A of output current. With a fixed switching frequencyof 500KHz, 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.PMU/tongbu/2019-11-01/444.html target=_blank class=infotextkey>CXSD6222 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. What is unique about PMU/tongbu/2019-11-01/444.html target=_blank class=infotextkey>CXSD6222 is that it is packaged in a tiny space saving SOT23-8 package
