I have a set of 3x "buck' converts doing 19Vdc to +12 / +8.5 / +5 Vdc.
I use a separate "power brick" to do the 120 Vac to 19Vdc / 4A conversion.
How do I safely "invert" the 12V and 5V power? Can I tether off the existing "buck" that I'm using for 12V and 5V? Or do I need to use two additional "buck" converters?
Attached is what I have so far.
I saw notes here:
Making a Voltage Inverter from a Buck (Step-Down) DC-DC Converter (maximintegrated.com)
But, still confused. Does the GND input on the buck now become an output?? Just want to integrate in with the same common ground.
