TMS320F28335: Is slope compensation supported?

Part Number: TMS320F28335

Hi Team,

The customer recently made a flyback power supply, and the design duty cycle is greater than 0.5, which will cause the problem of sub-harmonic oscillation. Does F28335 support slope compensation?

That is to say, is there a way to add a sawtooth wave with the same frequency as the control circuit on the slope of the inductor current, so that it can still operate stably when the duty cycle is greater than 0.5?

Thanks & Regards

Yale Li
