DPA Switch control current

Posted by: jdrocci on

What is the typial "idling" current requirement for the control pin on a DPA part?

Thanks

Joe

Joe: Please take a look at http://www.powerint.com/sites/default/files/product-docs/dpa_family_datasheet.pdf. Go to "control current at start of cycle skipping". thanks PI-Worf

Thanks Pi-Worf, however I still don't have a concise answer to my question. I'm trying to design a bias circuit that can supply the peak curent that the control pin requires during startup, as well as the average current it requires during regulation. I'm looking for ballpark design guidelines, not rigid specs. Thanks Joe

The control pin current ranges from about 6ma (under no output load) to 2mA (maximum duty cycle). Thanks. PI-Worf

Thanks Pi-Worf....that's exactly what I was looking for. Joe
