TPS61178: Is there an unencrypted spice model of TPS61178

ZSXKA

Part Number: TPS61178

I'm using the spice model of TPS61178 provided by TI.com ,but it's encrypted and cannot load into LTspice for simulation.

Is there an unencrypted model that can be used for LTspice?

Hi ZSXKA:

The model is not public yet. May you share your email address with me? Or you can send me a private massage.

Hi xie

Appreciate for you kind reply.

But the model you provided seems doesn't work in my simulation. I built a 7.2V-16V application accroding to the typical application in tps61178 datasheet with LTspice,it can not converge.

Can you help me check the problem?

Hi ZSXKA:

This model works well in pspice. I have no idea what happened.

May you catch the waveform of Vin, Icoil, Vsw and Vfb?
