Hello Everyone,I am trying to get into running the AD 6421A DC to DC converter to do some simple measurements.Since I do not have a ready evaluation module i have made one. As advised on the datasheet below.
The P_DIS mode pin is connected to the GND1 rail, to turn on the isolated output on Vcc2 side.It seems that the converter does not output anything on isolated side. No matter what settings I choose the chip does not output any power on the isolated side.
I have checked the power supply to the IC chips power legs, and there is stable 5 Volt supply on the Vddp and GND1 but on the opposite side nothing output of voltage. Thanks in advance
Dave Z: We have an eval board you could try if you put in a request for one from your company and info on your application. To investigate your board I would need to see your schematic and a layout, a photo of the board would help too. This could be shared by email.
Hello Brain, Many thanks for the reply. Meanwhile we have resolved the issue. And started to run some preliminary tests.Could you please share the infomation where I could order a such an evalulation board with ADUM-6421a.Regards
Dave Z: The ADuM6421A is not releasing until mid December. To order an eval board now you would need to contact your Analog Devices Sales representative or distributor.
