APPLICATION INFORMATION
If desired, the 60-Hz modified square wave inverter frequency could be programmed using an external sync
signal that might originate from a separate oscillator or digital controller. The following diagram in Figure 6 shows
a 50% duty cycle square wave fed into the CT pin, with a frequency of 120 Hz, and the resulting OUTA/OUTB
wave shapes.
