SN6507: Simulation Webench

Hi Rami,

We have Webench power designer for SN6507- you can find it in SN6507 product folder

Hi Rami,

SN6507 currently does not have simulation in webench.

See below for the beta version of the SN6507 and the companion transformer that was used for testing the model. Both models are included below.

• SN6507-20241101.zip - this is the actual model of the SN6507 transformer driver
• Wurth 750319696.lib is a model for one of the recommended transformers that can be used with the model for an initial test

Thanks,

Prateek

Hi Rami,

Please find the below inputs:

1. Leave the DC pin open for default duty cycle, (do not short it to ground) 

2. Leave the SR pin open for default Slew Rate, (do not short it to ground) 

3. Your simulation time is too short to see the output voltage- increase the "Run to time" in simulation window 

i. Since output cap is large (10uF) it is taking time to charge the output cap 

ii. You can try by removing the 10uF then you will get output fast.

4. Adding 50ohm between switch node and transformer pin is reducing the effective voltage across the primary side of the transformer due to which the output voltage will be reduced. You can try removing these resistor.

Let me know if you have further questions

Thanks,

Prateek

Hi Rami,

You have connected your output to gnd that's why it is showing zero. Connect a 0.1uF cap at output

Thank you   Prateek.
