Hi Marc,
Our reference designs are not available for ordering. We provide all of the files and you are welcome to make your own board using them.
Thanks,
Robert
Hi Robert,
Thanks for reply and yes we would like to make our own board to evaluate it.
May i request the datasheet for RLTI-1109 (Transformer, 100uH, TH from Reno Electronics) and G135036LF (Transformer, 30.5 mH, TH from GCI)?
Thank you,
No, the other way around. The winding on the power loop is 10, the winding on the signal loop is 1.
Thank you Sheng-Yang, i have below 2 questions regarding to the schematic connection for PMP9640:
Q1) There is a net connector labelled VSNS (pic below) but i cannot find where it is connected to, may i know if it is used in PMP9640?
Q2) Pin 4 of UCC28710D is labelled as GND but it is connected to BIAS at point A instead of point B at Ground, may i know if this is the correct connection?
Thank you,
Answer to Q1: Right, VSNS node doesn't tie to other place.
Answer to Q2: the connection is correct. We use UCC28710 on a high side Buck. And have the IC sit on the switching node. Therefore, the IC GND is tie to switching node.
