TPSM843B22: TINA TI MODEL

Vishnu

Part Number: TPSM843B22

Tool/software:

Hi Team,

please share this application circuit model of Tina TI or webench or LT spice.

2.How to add multiple output caps in TI webench, is it not possible to edit this automatic circuit.

3. Please share the simulation results of 50mV transient response as mentioned in datasheet. Also how to further reduce transient ripple to 30mV.

To meet the 30mV spec and simulate in webench:

In webench" Go to the left panel and scroll down and select "Custom Output Specs"

Update with new specs

Click redesign

The schematic is updated with new components.

Click simulate and select the simulation: startup, transient etc and click start.

Another method is use the model on product folder and PSPICE for TI

PSPICE for TI is the simulation tool for recent product releases.

Hi David,

Is it not possible to edit the circuit in ti webench?

0 David_Daniels 7 months ago in reply to Vishnu

Components can be edited to a different vendor and sometimes a different value, but not to add/delete components in webench

To simulate with mix of output capacitor, use the pspice model on product folder and PSPICE for TI can be ued.
