Ideal Diode for SEPIC SMPS

Thread Starter


Joined Sep 30, 2022

I am designing a SEPIC SMPS with a maximum output current of 6A. I would like to change the diode used in the SEPIC to an ideal diode using a MOSFET, similar to how the diode in a FLYBACK is replaced by a MOSFET. In the case of a FLYBACK SMPS, there exists chips specifically made for this function (ex, TEA1792TS). Is there a similar chip for the use with SEPIC?

My guess so far is to use the same chip and place the diode on the low side, though I have never seen similar circuits and I'm not sure if there is anything I am missing.
