LM73606-Q1: VRM model for buck converter

Hello

I am not familiar with that type of model.

Do you have an example of what you are looking for ??

Thanks

Hi Frank, 

These are for PI analysis. 

For example Analog Device provides the model for their DC/DC in LTpower CAD. For example a particular buck circuit with LTC3313 looks like this( shown below). The the equivalent circuit then can be plugged to VRM source in the PCB for PI analysis. 

Our customer somehow used  LM73606-Q1 from TI and we need to PI analysis, for which we need these info. 

Hello

At this time we do not have a model that we can provide for this device.

However, if you provide your application schematic and all the relevant parameters, we will try

to create a simple model for this device.

Thanks

The schematic is simple buck from 28V to 1.8V in one case and 3.3V in another case. Even though it is not that unique, we don't get consent from customer to share in public forum. We are stuck here for now. 

Thanks

Hello

Can you tell me the load current and switching frequency ??

Thanks

28V to 1.5V is at 6A and switching freq is 500kHz

28V to 1.8V is at 4.8A , sw. freq - 500kHz

28 to 3.3 is at 4.8A , sw freq - 1.2MHz

Is there is way we can calculate ourself too?

Hello

I will work on this and provide a model by Mon. 9/16/2024 PDT.

Thanks

Hello

Please see the following models.

Will you be using these models for load transients or some other high frequency testing ??

Thanks

Thank you

Yes these are for impedance analysis of power rails. 

How you arrive into these values?
