The Variable Switcher
The circuit diagram of the CA1524, used as a variable output
voltage power supply is shown in Figure 23. By connecting
the two output transistors in parallel, the duty cycle is
doubled, i.e., 0% - 90%. As the reference voltage level is
varied, the feedback voltage will track that level and cause
the output voltage to change according to the change in
reference voltage.
