LM74722-Q1: Pspice simulation

Vishwas H R

Part Number: LM74722-Q1

Hello,

I am trying to simulate the ISO 7637-2 pulse 1.

Why Vin is fluctuating if i consider load as around 20A.

If i take load around 50mA, then Vin is not fluctuating.

What is the reason behind this problem.

Hi Vishwas,

Can you share the schematics of the circuit that you are simulating.

Hi Praveen,

I considered the model available from Ti, only thing i changed is current will be 20A (13.5V) and input is ISO 7637-2 pulse 1.

Hi Vishwas,

Please share snapshot of the schematics or share the model files here for me to review.
