LMG3410R050: Issue with pspice simulation for TI

Hao Wen

Part Number: LMG3410R050

Hello,

I just downloaded the pspice for TI and ran the lmg3410r050 pspice model from TI website. The model is a buck converter but the simulation result is wrong. The switching node voltage of the buck converter is shown below. And the pspice file is also attached. Could you help me check what is the issue? Thanks!LMG3410R050.zip

Hello Hao,

It takes around 1ms for our part to initially startup (internal rail getting powered up and have right bias for the gate drive). If you make the time >1 ms (1.5ms for example) you should see the correct switch node waveform afterwards.

Please let me know if it works. Also we would appreciate if you could mark the answer as resolved if it solves the problem.
