Hi everybody ,
Please ref to the attached file for the circuit schematic.
I need advice where went wrong to this circuit, it could not fully drive the MOSFET to let desired current to flow !
I expecting 1.8A to flow through but only 1.33A, the LEDs (10W) are well attached with heatsink (individually), the temperature measured 43°C~45°C. The MOSFET flange temperature 30°C, I believe overheating is not an issue here.
The power supply is 24V 2.65A (SMPS adapter).
Thanks.
