Other Parts Discussed in Thread: LM5150RUMEVM
Dear Team,
We put two of LM5150 EVM board for dual source input.
The block diagram as below:
We found that the bypass FET on LM5150 #2 EVM board didn't turn on when #2 board input disconnect.
Why the VSG higher than Vth but didn't turn Q1 on?
The test procedure as below:
3. After VOUT is stable and change LM5150#2 power to 0V
4. Check the waveform of measurement point 1,2,3,4 when VIN of LM5150 #2 are changed
Thanks
Shaq.
