Tool/software:

I am using your part : LMR36503

I would like the most galvanic isolation is there a reference design? I am most concerned with the transformer and its orientation.

I want to check my design against your reference design. I want to maximize the galvanic isolation

Hi Phil,

The orientation for the flybuck looks correct, however this device is not a constant on-time control scheme. We don't have a readily available flybuck reference design using the LMR36503. We typically use a dedicated flybuck converter, like the LM5168 for these applications, which is a Constant on-time device. Please see the attached EVM

Thanks,
