目录7.相关产品 产品概述 返回TOP CXSD62505 is a high efficiency Buck converter with low power mode and output voltage select function. The output voltage can be changed by the VID0, VID1 and /LP pins with dedicated setting slew rate. It therefore supports dynamic voltage scaling function target.The CXSD62505 operates over a wide input voltage range from 2.5V to 5.5V. It is available in a QFN3x3-16 package.产品特点 返回TOP
