Hellow,I got stuck with this problem for a long back. I used an EPC9150 for the project and adjusted the Vlogic input voltage to 6V, VBus input voltage to 6V, and Input pulse to 3.5V with a pulse width of 80ns. However, no voltage was detected in the EPC9150 Vout, VGS, and CAP.How should I use it。
Hi
Because there is no load soldered in the right side of the board, Vout and CAP without signal is normal. Can you share the waveform of Vgs and Vgdin?
And please make sure the switches on the board are set correctly.
I move the jumper on J4 to the leftmost position and move the jumper on J8 to the down position. I will share the waveform of Vgs and Vgdin on Monday.Thanks for you reply.
