Hi,
In this schematic I use LEDs as load. When I unplug the power supply from 220V I have a fast blink in LEDs(a delay to switch over battery) but when I disconnect the 5V(VCC) there is no problem and battery switch immediately. With Scope I see voltage decreasing over the gate of the mosfet and maybe the curve making this problem. Is there any way to solve it?
