TINA/Spice/PMP10783: Buck converter - PMP10783

Bipin Panchal

Part Number: PMP10783
Other Parts Discussed in Thread: TINA-TI,

Tool/software: TINA-TI or Spice Models

I am simulating the PMP10783 design on TINA same as schematic of PMP10783 but why output voltage is not coming? VDD voltage is increasing to UVLO level and again going down and turns off IC.1715.PMP10783_startup.TSC What can be reason for that? why

what can be a problem? is it a design problem or TINA tool problem?PMP10783_startup.TSC

Hi Bipin,
Thank you for your inquiry. I'm currently working internally to find out what's caused problem.
I would appreciate it if you could wait little more time.
Regards,
Yuki

Hi Bipin,

I'm the design engineer for this project. I didn't use TINA to do the circuit simulation. Instead, I simulate the circuit in Simplis. You can download the intro version from Simplis website (simplistechnologies.com/) to run the simulation file I have attached. The PMP10783 has been tested and verified, so there must be some setting not right in the simulation.

Thanks Yuki for attending the query. I am attaching little updated TINA file.PMP10783_SS_20170223_ok_B_full.TSC
