cn说说明明TWL1200-Q1是一款19-位电压转换器,此转换器专门设计用于2.
6-V基带和TIWi-Link-6(WL1271/3)间1.
8-V/2.
6-V数字开关兼容性差异的无缝桥接.
此器件针对SDIO,UART,和音频功能进行了优化.
TWL1200-Q1有两个电源电压引脚,即VCCA和VCCB,这些引脚可在1.
1V至3.
6V的全电压范围内运行.
TWL1200-Q1能够使系统设计人员轻松实现从应用处理器或者数字基带到运行在不同I/O电压电平上的外设的接口连接,例如到TIWi-Link-6(WL1271/3)或者其它SDIO/内存卡的连接.
TWL1200-Q1采用薄型四方扁平[TQFP(PFB)]封装.
低静态功耗以及小封装尺寸使TWL1200-Q1成为移动电话应用的理想选择.
