Hi,

P/N:TPSM843B22E for 5V/20A and 3.3V/20A O/P Voltage requirements Input Voltage is 14 to 16VDC.

How and where i can get the Circuit with full simulations results.so that i can get the all required components part no and values.

This is a all time question for me, once part no is selected how to configure the Circuit for the Required specification within ICs Max. limitations.is there any option to generate/simulate the Circuit and BOM from only having the TI IC Part No.

Mahadevan Velvalli,

The TPSM843B22E is a variant of TPSM843B22.

Webench of TPSM843B22 can be used to calculate components, generate a BOM and simulate startup, transient, here is a LINK to the webench model.

Hi David,

How to use to web bench??? Now i have the Part no, using this part no i have to get the Circuit with all necessary values. Normally web bench is supporting for the new design search with our parameters??? if i have the part no then how can design and simulate the circuit in web bench Pls guide me with step by step process.

For some reason the link disappeared on previous post. I added it back

At the bottom of the TPSM843B22 product folder there is an intake panel for webench

enter your input voltage output voltage and output current.

Click Open Design

A new panel will open with schematic.

The Change optimization button can used to optimization for "small design" highest efficiency" "low cost"

The default setting is "balanced"

The left panel has further configuration settings: switching frequency, soft start, transient, etc

Click Simulate to simulate load transient, startup or input transient.

Use export to download .pdf report or download the BOM

If this device does not meet a requirement, you can go to https://webench.ti.com/power-designer/

Enter the input, output voltage and output current and click view designs and several solutions will be presented
