Forum Post: RE: LM5116 60-90V to 55V 50A
HiIs there a special reason you have to use IGBT rather than MOSFET ? You may need power diodes in parallel with your IGBT in addition.Regards,

The Vout and Iout equations will be quadratic in form as shown in EQ 8. For figure 7, I calculate Vout = [12 +/- SQRT(12^2 - 4 x 4ohm x 5W)] / 2 = [12 +/- 8] / 2 = 10V or 2V. Vout = 2V is the correct...
