Part Number:LMP7701
Tool/software:TINA-TI or Spice Models
I am making a voltage control current source with LMP7701 opamp and MJH6284 darlington pair transistor. I want to drive a current of 10 A peak to peak @ 100 KHz and 1 A offset. I have overshoot on my current pulse, I checked the phase margin by braking loop ~89 deg noted. I don't understand why I have overshoot even with this good phase margin. I have attached circuit I used for checking the stability and with actual circuit for reference.
