PRODUCTION DATA
The power stage of the device is shown in the block diagram, and a simplified single phase circuit is shown in Figure 9-4. When operating, the device switches at a 50% duty cycle with Q1 and Q3 turned on and off at the same time, while Q2 and Q4 are turned on and off simultaneously. This results in the following equivalent circuits.
