PCC Modulation Terms
PCC modulation is noise sensitive. The On-Time is unpredictable and has to be overall controlled:
D > 50% causes sub-oscillations that must be damped by peak current reference Slope
Compensation
A too short On-time might damage the MOSFET
A too long On-/Off-Time needs to recover via time-out.
