"Class C" line harmonic distortion

TEA1716, certain IC production lots have jump instability between 125KHz fixed frequency operational state, and normal fixed Ton state with valley skipping.


This is causing current spike near zero crossing, which is causing Class C line harmonics failure.


How to fix this instability?
