I have very limited experience with building circuits.
I bought the Q015-5 Converter to bring the 5V supply from the Arduino Uno R4 to 150V and I am having problems with laying it out on my board. I’m pretty confused as to which part is Vin and Vout because I’ve set them up multiple ways, but my multimeter is not reading any voltage output at all.
Which leads are supposed to be connnected to which inputs and outputs?
Hello @dominique,
You have likely seen this pinout from the datasheet:
I don’t know if this will work as described as initial start-up current may be a problem. While the Q015-5 is rated for 100 mA (no load) and 250 mA (full load), there may be higher current as it turns on.
Know that the 5 VDC rail on an Arduino R4 WiF is derived from the VBUS of the USB connection (see schematic). Consequently, the Arduino’s power supply could also be an issue.
Recommend isolating the DC-HVDC converter from the Arduino. Use a bench type power supply if possible. Once it is working you can revisit the Arduino.
Sincerely,
Aaron
Thanks Aaron!
I was considering powering rhe Arduino board with a battery, do you think that would work or do you think I absolutely need a bench power supply?
@dominique I believe that Aaron is suggesting to use a bench top power supply to test the part before incorporating the Arduino. This was you know the current draw of the part and how to connect the part. The Q015-5 may need a load on the output in order to measure the output voltage.
Oh I understand now! I’ll do that first.
