Application Information
(Continued)
appears across C6 when the switch is closed. When the
switch opens, C6 is referenced to the 8V output minus a
diode drop, which raises the voltage at C6 with respect to
ground to about 24V. Hence, in the fourth stage, C7 is
charged to 24V when the switch is open. From the first stage
to the last, there are three diode drops that make the output
voltage closer to 24 - 3xVDIODE (about 22.8V if a 0.4V
forward drop is assumed).
