TPS53681: CSD95490Q5MC设计6+1 phase两电源输出,channelA(6phase)输出值与设置的(DBh)值不符,channelB (1phase)输出值正常

Part Number: TPS53681

用TPS53681设计一个(6+1 )phase两电源输出;

使用Fusion Digital Power Software 识别不了TPS53681,但PMBUS(I2C)读写操作正常;


channel A:  0XDB  写入 0X73(输出应该为0.82V),但实测只有0.705V;

 channel B:  0XDB  写入 0XBF(输出应该为1.2V),实测1.195V,正常;
