Hi Unnimaya,

No, the Lm25185 does not support the two-switch flyback. You will need a circuit that has two gate outputs.

Thanks,

Richard

Hi Richard,

With 2 Lm25185 IC, can I drive the 2 switch flyback?

Thanks and regards

Hi Unnimaya,

No, that is not recommended since there is no easy way to synchronize the two gates due to tolerances in the internal error amplifier.

Thanks,

Richard
