A description of the comparator pins is given below:



Pin 24 OUT_PI[3]: positive input of the COMP3. It receives the output of the analog PI

current.



Pin 25 OUT_PI[2]: positive input of the COMP2. It receives the output of the analog PI

current.



Pin 26 OSC: negative common input analog COMP2, 3. It receives the reference

triangular waveform.



Pin 27: positive input of the COMP1. It receives the sensing signal of the total input

current.



Pin 28: positive input of the COMP0. It receives the sensing signal of all switch

currents. COMP0 stops driving when an overcurrent occurs in any switch.

Driving and interleaving

The STNRGPF01 PWMs for channel driving are pins: 1, 4, 5, 8 and 16. Figure 7 shows the

configuration for PWM generation.
