Part Number: LM26420-Q1 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Why TI official website doesn't provide the LM26420-Q1 average model?
I had try used the WEBENCH to get the loop response curve, but I can't add new…
Chandan,
It appears that LM26420-Q1 only opens up in the old Flash based Webench. For some reason the input voltage is being changed to 14 to 22 V and the design is not created. So far as I can tell LM26420-Q1 is not yet supported in the HTML version…
Part Number: LM26420-Q1 Hello,
Figure 33 of datasheet (SNVSB35) shows Power Good Hysteresis Operation. In the text above referring to Figure 33 it says : "..., it is not pulled low until the output voltage exceeds +- 14% of the setpoint for a....".…
Hello John,
Thanks for the support!
I am Chaitanya Rathi working with Sreejith on this project.
Adding 2x100uF caps is not a feasible option for our design. Do you have any other solution for reducing spikes on 2.2V?
As mentioned earlier by Sreejith…
Part Number: LM26420-Q1 Dear, Sir.
My customer is considering to apply LM26420-Q1 by fSW=2.2MHz.
They need like FPWM to avoid Radio noise issue.
So, Iwould like to confirm LM26420-Q1 has the automatic mode change from PWM
to PFM under light load. …

Part Number: LM26420-Q1 Tool/software: WEBENCH® Design Tools Hi All,
The Home Page states that LM26420-Q1 can be exported to TINATI on WEBENCH.
But there is no SIM EXPORT screen.
When Ch_1 or Ch_2 of the following image is selected, SIMEXPORT is displayed…

Tool/software: WEBENCH® Design Tools
We would like to use WEBENCH using with LM26420X-Q1 at following 4 cases.
But WEBENCH doesn't work in these conditions.
CaseA
3.3V-> 1.8V( to 0.25A)
1.5V( to 1.4A)
CaseB
3.3V->…
