Electronic load, Problem turning MOSFET on
At this point the MOSFET is on, and allows approximately 250mA to flow through though.
Any ideas on what this could be?
Things I have tried:
- removing R6 and Q1 and connecting R8 to -In. … .
- Changing the FET
- Raising the resistance of R6
On a side note, there is one way that I can get the load to be variable, and that is by removing the heat sink from the MOSFET. …
