45. Switching <strong>Stabilized power supply circuit</strong> Part 3.gif

It uses a V MOS tube with high input impedance and high transconductance as the adjustment tube, which can
greatly simplify the entire circuit. When the input voltage of this power supply changes from 150 to 250V, the output voltage is -12V, the current is 0~2A,
the voltage stability is <1%, and the ripple voltage is <8mV.
