用了3个TPS40400,PMBus address分别是00, 06, 60, 但用TI的USB Interdace Adapter, 使用软件Fusion digital Power designer,只能识别到其中的一个地址为60的,想知道一下原因,感谢!
Johnsin Tao:
HITPS40400地址描述见datasheet第10页:The TPS40400 has 64 possible addresses (0 through 63 in decimal) that can be assigned by connecting resistors from the ADDR0 and ADDR1 pins to SGND. The address is set in the form of two octal (0-7) digits, one digit for each pin. ADDR1 is the high-order digit and ADDR0 is the low-order digit.
