Figure 13. Voltage Inverting Converter (Note 7)
Typical Applications (Continued)
Note 7: This is a typical inverting converter configuration. The working process in the steady state is similar to
step-up 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 V

=V
OUT
*R2/(R1+R2)=1.25V+V
OUT
, so the output voltage can be decided by
V
OUT
=-1.25*(R1+R2)/R1 (V).
