As shown in figure 1, the standard application of the AN8032 is a booster chopper circuit, which inputs
It controls so that the input current proportional to the input voltage (C, D in figure 1) could be flown.
The reason for selecting the output voltage of 400 V is that the withstanding voltage of components and
