Thank you. This explanation is at my level. :) I make sure nothing overheats as I used it. But I wondered why the op amp failed before. I did notice the 5V supply consuming twice the current as I turn R2 to increase the current thru the MOSFET. That is why I am worried if there is lacking in my circu... (more) |

Sorry I wasnt clear in saying that I am making a constant current load tester. From what I understand from the maker of this circuit. I need R1 to be low, and the oscillation at the gate of the MOSFET makes the current constant. (more) |

I changed the link. This is for a constant current load tester, for batteries and testing the current rating of buck converters. It works with the load negative connected to ground. MOSFET source resistor is 1ohm. No op-amp supply decoupling. (more) |

Hi, related question: if relays need diode why arent they fitted with it as a unit? (more) |
