Hi Team,

I am simulating the LM5156-Q1 using Lt-spice but I am not getting the gate voltage in simulation.

Please can you check and let me know? What issue is the issue I am facing let me know.

Hi Suma,

I am not sure if this is caused by LTspice.

The signals you applied to CS and FB is not proper.

Hi Feng

Kindly send me the P-spice simulation working document for the IC.

Hi Suma,

I think you may build the simulation referring to the LM5156 boost EVM schematic: https://www.ti.com/tool/LM5156EVM-BST
