| LTspice...wish to split LT1243 output into two separate pulse streams |
| (1/1) |
| ocset:
Hi, I wish to simulate a Half Bridge SMPS in LTspice, but using the LT1243 adapted to control it. I need to split the gate drive in to two separate streams as in the attached. Would you say D flip flop for each stream would be best to achieve these two streams? |
| ocset:
The attached (LTspice and schem) shows how it can be doneā¦but I am getting an unfortunate little spike in the waveform streams as shown. Any better ways? |

The spike is caused by pulse front leaking from input. You can replace your voltage TTT and SSS and both switches with 2 AND gates. Wire LT chip output to 2 inputs of 2 AND gates. Other inputs of AND gates go to Q and #Q of flip flop. |
