Part Number: LM51772
In one of our projects, we used the LM51772RHAR to make a stable output voltage that can be changed by the I2C interface.
We did test with the device, and the output voltage can be set by I2C without problems.
But we also…
Part Number: LM51772 Tool/software: Hi,
I was able to enable LM51772 and tested with good performance. However, I made another PCB with same schematic design but encountered the issue that the output is abnormal (5V output as captured below). And…

Hello,
Everything was fine with my new PCB. I could control Lm51772 over I2C and suddenly I have NO Vout. 0.000 V
EN pin sits above 2.2 V.
VCC1 and VCC2 are both 5 V.
with the scope…
