Hello Kuan,
If you are referring to PFM mode of the LM5165, then you are correct, the LM5164 cannot be used in PFM mode. However, the LM5164 employs a Constant on time (COT) control scheme similar to the LM5165. COT is a modified hysteretic scheme…

Is there an issue with placing a capacitor across the bottom feedback resistor on the LM3489?
I had this circuit and it was trying to switch at 1.5-2MHz, so I added a 470pF across R6 to slow it down and it…
