Other Parts Discussed in Thread: LM5146, LM5145-Q1, LM5145
I have tried to simulate LM5146 in Pspice. As per my design calculation I have programmed IC. But high side drive is not functioning.
Please check voltage as per bellow attached schematic which is 1uV at HO pin.
Design specification :
- Vin 30V to 60V
- IOut limit=30A
- Softstart time =18ms
I have done transient analysis as well.
I am not getting pulse on HO pin (blue colour) & getting initial 1 pulse at LO pin (Yellow colour) .
Kindly help to simulate the model.
