I would like to use the MP8009A PoE DC/DC in our design, but my adapter’s power range is 8V to 36V and the MP8009A’s auxiliary power ranges from 8.8 to 57.
My question is: can the MP8009A work with my adapter which has a Vrange 8 to 36 V?
Thanks in advance
Should work, the gate drive to the FET will be a bit low, so you could use a logic level fet there. Get a demo board and play with it. The issue I presume is the 800mV bretween 8.8 and 8?
The VCC regulator will be in drop out, but reading the datasheet I don’t see anything suggesting it will stop until the VCC falls all the way to 6V.
