Part Number: PMP22477
Other Parts Discussed in Thread: TPS23730

Dear All,

has the PMP22477 ben tested with FDMQ8205A active bridge?

Can you share the results of efficiency with FDMQ8205A regarding to the diode bridge solution?

Also can the FDMQ8205A  work for TPS23730 PoE PD  802.3bt Type 3 Class4 40W, without any issue? 

Best Regards,

David.

    Hello David, 

    No we have not tested PMP22477 with the active bridge. Testing this would require a layout change. However, we know that an active bridge will work since this is related to PoE, not the DCDC design. It will improve efficiency about 0.5%-1%, depending on load. 

    If this post answers your question, please indicate so by marking this thread as resolved. Thank you.
