Other Parts Discussed in Thread: UCC27289, SN6501
Hi,
We found there is about 6V on HS when LM25101 is used to driver the high-side and the low-side N-Channel MOSFETs in a synchronous buck. The VDD is 10V.
It can be pulled down to 0.3V with paralleling a 10K on HS to GND.
We removed the MOSFET and the voltage on HS still exists. The leakage current on HS is about 60uA.
Does it be normal? Or how to fix it ?
The same phenomenon is on UCC27289
