Hi Alfonso, I realised that TPS62172 part might not be the best solution because it goes to a power save mode at light loads. I think I need a fixed frequency dc-dc for a wireless application. Maybe part TPS62561 would be better? I couldn't find an IC…
Hi Felix,
You could use PSPICE model available on www.ti.com/.../toolssoftware for TPS62561.
If required I can share the unencrypted PSPICE model with you over email and procedure to import model to TINA-TI can be found at link below:

Thanks for explaining.
If you want to debug the issues with the power save mode, you can post some waveforms and your setup. Did you already use a feedforward cap to reduce the PFM ripple?
TPS62561 is one option. There are also other options in…
Hi Tanvee,
Thanks for the answer.
Looking at alternatives you suggested in SOT-23 I saw: http://www.ti.com/power-management/non-isolated-dc-dc-switching-regulators/step-down-buck/buck-converter-integrated-switch/products.html#p238min=1.5;4.5&p238max…
