PWROK
System power good input. When this pin is high, the SVI
2
interface is active and I C protocol is running. While this pin
is low, the SVC, SVD, and VFIXEN input states determine
the pre-PWROK metal VID or VFIX mode voltage. This pin
must be low prior to the ISL6265A PGOOD output going
high per the AMD SVI Controller Guidelines.
PGOOD
Controller power-good open-drain output. This pin is typically
pulled up externally by a 2.0kΩ resistor to +3.3V. During
normal operation, this pin indicates whether all output
voltages are within specified overvoltage and undervoltage
limits and no overcurrent condition is present. If any output
voltage exceeds these limits or a reset event occurs, the pin is
pulled low. This pin is always low prior to the end of soft-start.
我英语不好!你要能翻译的话告诉我一下!
另外ISL6265A的资料也发上来,有需要的下载看看!有英语好的把引脚资料翻译一下分享给大家!谢谢了!
