1) Application outline

As shown in figure 1, the standard application of the AN8032 is a booster chopper circuit, which inputs

the voltage rectified from the commercial supply of 100 V/200 V (A in figure 1) and outputs the DC voltage

of 400 V (B in figure 1).

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

the operation limitation of booster chopper (input voltage < output voltage) under the worldwide input voltage

are taken into consideration.
