Product Number: LTC3880IUJ#PBF
Software Version: LTPowerPlay Build1.8.0.0
Hello
Recently, I started debugging the LTC3880.
I checked the VIN=12V, INTVCC=5V, VDD33 = 3.3V, VDD25=2.5V.
In the Project file, I had set VIN_ON=6.5V, VIN_OFF=6.0V
I'm using USB to PMBus tool DC1613A.
The LTC3880 Data sheet, Vin is larger than VIN_ON, SHARE_CLK pin is toggling. But. it does not toggle.
and two Run pins are low.
I think that internal ADC doesn't work.
How can I proceed?
If you have any golden project file for the device.
I would like to use the device as two 1.0V/10A power supply.
Best regards.
Hwang.
