TYPICAL APPLICATION USAGE

The ADuM1230 is intended for driving low gate capacitance transistors (200 pF typically). Most high voltage applications involve larger transistors than this. To accommodate these situations, users can choose either a gate driver with a stronger output stage or the buffer configuration with the ADuM1230, as shown in Figure 14. In many cases, the buffer configuration is the less expensive of the two options and provides the greatest amount of design flexibility. The precise buffer/high voltage transistor combination can be selected to fit the application’s

needs.
