TYPICAL INVERTING CONVERTER CIRCUIT
This is a typical boost converter configuration. The working process in the steady state is similar to a boost converter,
the difference in this situation is that the voltage at the non-inverting pin of the comparator is equal to 1.25V +V
then Vpin5 = V
OUT
*R2/(R1+R2) = 1.25V, + V
OUT.
The output voltage can be decided by V
OUT
= -1.25V*(R1+R2)/R1
(V).
