| Jul 30, 2018 at 17:19 | comment | added | Peter Kapteyn | Thanks for your answer. I tried using this FET with a lower input capacitance and gate charge: nteinc.com/specs/2300to2399/pdf/nte2371.pdf however it didn't change the result at all. The load is a SMPS driving a high power LED. I removed R1 and increased the value of R5 so that current would charge the FETs gate capacitance faster but to no avail. | |
