I have synchronous Step-Down Voltage Regulator drives by LM76003
500kHz FB have reference voltage 1V.
This power supply has power two Independent Load and I wonder how to switch feedback network pro FB input LM76003
if first load not used FB1 have high impedance.
The question is how switch On/Off FB2?
Small signal relay, OK but relative lagre solution
Analog switch, maybe, but what? In device is not negative voltage for power analog switch.
