Hey all,
I have a circuit which runs off a wall wart @~12vAC. I have rectifier(DB107S), and a few other components to produce a value @~5vDC. This circuit is used to drive an ESP8266 on a regulated 3.3v board, leaving the 5v to drive an LED strip.
Now, when I don't have the ESP plugged in, and the VCC/GND for the socket the ESP plugs into connected to my o-scope, I see the following values:
Vamp: 400mV
Vmin: 4.80V
Vmax: 5.20V
When I plug the ESP module in, I see:
Vamp: 4.80V
Vmin: 400mV
Vmax: 5.20V
Doing some testing, if I supply the DC side of the equation directly, everything works as expected. Also, if I supply ~12vDC to the entry point on the board, everything also works.
Can someone explain why the switch between the Vamp and the Vmin?
My head says thank you
Paul
