Hi support team.
I will use LTM8063 as a negative converter.
Schematic is very similar to datasheet p.20(-5V circuit),and PG pin is pulled up to external +2.5V.
However ,in this case PG pin low voltage goes -5V level.
So I want this [-5V - +2.5V] to convert [0V - +2.5V].
What is the recommended circuit to achieve this?
You can try a shottky diode cathode on PG and anode on system GND.
Thank you for reply.
That's a simple solution!
If it seems to require higher speed, i will try i-coupler solution.
i-coupler can't be apply -5V-2.5V voltage...sorry.
