Other Parts Discussed in Thread: TINA-TI Hello,
I'd like to perform simulation of LM536035-Q1 in FPWM mode on the Webench, but it seems that only AUTO mode is available currently. How can I perform the simulation in FPWM mode?
Best regards, Shinichi…
Part Number: LM53603-Q1 Hello,
I'd like to accurately estimate the Max dropout voltage of LM53603-Q1 under the following conditions.
Output voltage drops down to 4.95 V.
Output current: 3 A
Switching frequency: It is acceptable that f SW goes…
Hi All,
The data sheets are listed as follows.
(4) The maximum recommended output voltage is 6 V. An extended output voltage range to 10 V is possible with changes to the typical
application schematic. Also, some system specifications will not…
Other Parts Discussed in Thread: LM53603-Q1 , TPS54060 , LM53603 , LM536035EVM Can someone make an educated assumption about tr an tf of LM53603-Q1? Their values affect IC Power dissipation. For example in Application report SLVA317B the author made an…
Other Parts Discussed in Thread: LM53603-Q1 , LM53603 Dear support team
My customer evaluate LM53603-Q1 using EVM.
In frequency response data, Gain prot starts from 0dB at Vout=3.3V Iout>1A (see attached file.)
Is this normal operation?
Could…
Hi Akhil,
Thanks for reaching out with your question and for considering the MC33063A in your design.
Based on your specifications I don't think that the MC33063A is going to be the best choice for your application. I think something like the LM53603…
Other Parts Discussed in Thread: TINA-TI , LM53603 Tool/software: TINA-TI or Spice Models Hi, i am working with LM53603 buck regulator, i need simulation of my design but i give *invalid device:$CDNENCSTART$ error, i think model is encrypted, is there…
I think it is ok to use the LM53603 Rdson as estimation. But the FET design is not exactly identical, they are similar.
For low Vin PFM transition, yes when Vin is lower, the build up of the offset takes time, how many cycles depend on the operating…
Hi,
Webench does estimate the light load behavior and you can see the effect on the Efficiency curve. As the load current decreases you will see an inflection on the curve and the efficiency will start to flatten out.
At this point the part is lowering…
Hello Matsumoto-san,
The figure 21 in datasheet is correct and is based on measurement data and not simulated results.
The efficiency for Vin=18.0V, Vout=5.0V and Iload ~10mA has been confirmed to be just <90% (see attached spreadsheet).
I used…
