LM63635-Q1: Pspice model

Other Parts Discussed in Thread: LM63625-Q1

Dear Sirs,

We are trying to design a 24V to 5V, 3A DCDC converter using the LM63635-Q1 controller.

Unfortunately, there is a problem in the simulation model of this controller in variable frequency mode. The model works only in the fixed frequency mode of 400 kHz and 2100 kHz. The controller model LM63625-Q1 does not have this problem. Can you fix the LM63635-Q1 controller model for variable frequency simulation?

Thanking in advance for your help

Hi Mikhail,

I am still waiting for confirmation from the modeling team. Sorry for the delay.

You may be able to use the LM63625 model, with reduced current, in the meantime.

Regards, Jason
