数据： TPS40428 支持自适性电压调节 (AVS) 总线的双路输出、双相、堆栈式 PMBus 同步降压无驱动器控制器 数据表 (Rev. A)
TPS40428器件是一款PMBus同步降压无驱动器控制器。其出厂默认设置的工作模式为智能功率模式，在进行PMBus编程并重启电源之后即可在非智能功率模式下工作。该器件可配置为双路输出或双相操作。而且该器件最多可堆叠4个相位，支持高达120A的负载电流.2相，3相或4相交错式相移可减少输入和输出波纹，从而减小输入和输出电容。
它的宽输入电压范围可支持5V和12V中间电源总线。基准电压精度达0.5％，可满足现代专用集成电路（ASIC）对于精准电压的需求。
根据PMBus标准，TPS40428器件可对基准电压，故障限制，UVLO阈值，软启动时间以及接通和关断延迟进行编程。
此外，该器件还实现了精准的测量系统，用于监视各通道的输出电压，电流和温度。
