The configuration to create the PWM signal in the FPC is basically the same as the circuit in the PDF. I checked the signals at the 5223 op amps and everything is the same. I called them comparators but I meant they were op amps that were also being used as comparators. Read through the PDF to understand how the circuit works. Here are pictures of both the square and triangle waveforms created by halves of the two 5223 op amps in the FPC. Square
