UCC256404: Schematic review request

Willem van der Kooij

Part Number: UCC256404
Other Parts Discussed in Thread: UCC256304

Hi,

In the past week we have converted an existing design using the UCC256304 to the UCC256404 and I would like a schematic review if possible.
We have tested two modified PCB's which mostly work fine except that the burst mode never enables at low output load. The paragraph in the datasheet to program the burst mode threshold is pretty ambigious and therefore we would like some help, can we e-mail the schematic to someone for review?

With kind regards,
Willem

Hi Willem,

I can review the schematic for you. I sent you a connection request through E2E. You can direct message the schematic to me for review.

Best Regards,

Ben Lough

Hi,

I've been in touch with the expert and got the design review. In my case I needed to increase Rll/ss_lower more to increase the BMTL threshold.

Thanks for the support.

With kind regards,
Willem
