Product Number: LT4294
I've arranged the DC2583A (LT4294) and DC2660A as DCDC (LT8646S) boards as shown:
Then I've connected the SW-525 PoE switch + 48V/100W Power Supply and an electronic load for the LT8646S 5V output.
- Jumper selection are set to JP11 and JP12 (40W PD Class 5)
- PoE Auxiliary input is not used (left unnconnected)
- LT4294 PWRGD is connected to LT8646S EN enable pin
The problem is I'm not able to get 5V@8A (40W) from the whole system as expected. In my case the maximum power I can deliver to the load is 22W. Why?
Any help from ADI support?
regards,
