PMP4190: 3-V to 6-V DC input, 5-V/0.5-A, 1-MHz isolated flyback reference design

Navi Singh

Part Number: PMP4190
Other Parts Discussed in Thread: TPS61175, , TPS55010

I have simulated PMP4190 using of TPS61175 simulated board with Tina Software.

First I select TPS61175 buck converter and simulation is OK than I am draw circuit PMP4190 using TPS61175 Simulator Board in TI. My Simulation Boards is not working-

I have doubt transformer selection-

I have select two transformer- 1. Take transformer in library and 2. 750311880(Take- Wurth TPS55010)

Hi Navi,

Sorry for my delayed response. I am not an expert at using TINA. I am trying to find an appropriate person at TI to help respond to your question here.

thanks,
Brian

Hi Navi,

I have modified below boost converter schematic (TPS61175 TINA-TI Transient Spice Model) for flyback operation. See below for file and waveforms. Based on your input and output parameters, you change the power stage parameters. I would recommend you to check POWERSTAGE-DESIGNER tool.

About your TINA schematic- I need to look more closely. The transformer you used doesn't include any magnetizing inductance. It maynot work as you expect. Below is picture of the transformer model I used. I had added leakage and magnetizing inductance to an ideal transformer. Let us know if this helps.
