How to validate the buck converter design using TINA TPS65251

Hi

I have created a design using the Triple switcher I have calculated the inductor capacitor values and compensation values for the design requirements in my design

There is no we bench support  for the design how to validate the design using TINA what are analysis to be done for it and how to do it slvm512.tsc

  • AGXIN,

    Are you asking what to simulate to verify a power supply design?

    The design verification process for any power supply is complicated and varies from project to project. You must identify what the key care abouts are for your system and verify that you have met those needs.

    You have done the first step by identifying the voltages and currents needed and calculating the values for the components. You will want to make sure that your design is stable across the expected operating range (the average model can help you check this). Once you have verified that your system is stable, you will want to verify the performance of the system.

    Running a quick simulation that shows the output voltage values are as you would expect will confirm your component values. If there are changes that are required, you may have to iterate on the previous steps. Next, you will need to know what will change in your environment (variation). Simulation can verify that your design will perform within the expected variation of your power supply needs (component variation, load/line variation, etc.). Yu will need to identify the conditions that must be tested. Any changes to the design will require a quick iteration of the previous tests.

    Once you have a robust design that meets the performance requirements in your simulations, you can then move to the prototype stage. Simulation can only provide insight into the system, but a prototype will give you real world information. Your layout will impact the electrical performance of the system as will the parasitics that were not used during simulation (you may identify additional cases you need to test and you may have to re-run your simulations with additional information obtained). Assuming that you have a prototype that has been tested and is a good representation of the solution required, you would then be ready to look at the production of the system.

    Unfortunately, I cannot tell you what to verify in simulation as that is dependent on your task. You will have to identify and quantify the requirements of your system and use your engineering knowledge of how to adjust the design to meet the required specifications. There are many good resources available on the web that can help with power supply design and what steps to follow. But remember, these are suggestions that may or may not apply to your specific situation.
