Post-filter feedback on IRAUDAMP9?

[proplayer69]

Anyone here tried implementing post-filter feedback on the IRAUDAMP9 or any IRS2092-based design? I'm aiming for a stable PFFB setup using only passive components. What kind of compensation network is needed to correct phase margin and keep the loop stable? Any tips or example values would be really helpful.

Additional questions: How does PFFB affect the self-oscillating frequency?

Is it a good idea to use the asymmetric switching (parallel resistor-diode) control in MOS gate than only resistor in series?

Newbie here, just looking for some advice from the experts. Thanks!:]
