Hi Gerhard,
This design needs to supply 3 A continuous, correct?
I would call this more of a corner case design and WEBENCH does not always handle these the best so some hand calculations are needed. For this example a very high amount of input current…
Other Parts Discussed in Thread: LM2588 , TPS43060 , LM5122 , PMP7979 I am looking for a high efficiency solution that will output 48V @ 4A max with input of 11-30v. Any tricks to coax that much wattage out of the latest chips?
If you want 5A load current, use the following ref which is closer to your application. You just need to adjust the low side resistor at the FB pin to correct the output voltage to 48V.
Thanks,
Youhao
