Re: Identifying an SOT23-6 with marking JWF9R
I agree with "jiroy".
Probably chip JWF9R from evaluation board and it doesn't sell.
"R_J" - Your option with chip JW1251O is quite simillar to JWF9R.
If someone will find datasheet on JW1725O with output numbers and designations I'll be apriciated.
It's close enough with JWF9R as well.
Thank you.Leave a comment:
