Part Number: LM3485 Dear TI partner,
My customer use LM3485 for a buck application, basic case is input 24v, output is 12v/3A; the schematic and pcb as below
there are several question need to be consult.
1.why our datasheet typical application is different…
Part Number: LM3485 Other Parts Discussed in Thread: TINA-TI ,
Tool/software: TINA-TI or Spice Models
I got the error "Irregular circuit" when simulating in TINA a circuti based on the Spice model of LM3485.
Error and circuit can be seen in the…
Part Number: LM3485 Other Parts Discussed in Thread: TINA-TI
I have an assignment for electronics engineering on the LM3485 and I would like to analyse the buck controller circuit in Tina-Ti
There doesn't seem to be a Tina-Ti model Un-encrypted…
Part Number: LM3485 Tool/software: WEBENCH® Design Tools Aided by Webench, I designed a buck DC/DC converted based on the LM3485MM/NOPB
- Input DC 20 V - 25 V
- Output:12 V at 2.5 A
Once manufactured the DC/DC converted, it is not protected against short…
Part Number: LM3485 Hi, I have a problem with LM3485 switching frequency. I made simulations in WEBENCH, in LTspice and everthing was ok - frequency was about 409 kHz. So I've designed custom board with LM3485 buck DC/DC converter 24 V - 5 V (max 2 A) I…
Part Number: LM3485 Tool/software: WEBENCH® Design Tools Hello,
I have developed one power supply in webench, and now I want to export that into TINA, But in webench, I don't see the option of sim export. I can see only of CAD export. How I can export…
Part Number: LM3485 Other Parts Discussed in Thread: TPS53119 Hi,
I want to use this device because of the hysteretic feature but my design requirement is I have to drive a specific N Channel Mosfet. Is it possible to do this in a Buck Topology?
Part Number: LM3485 Hi
Out customer evaluates LM3485 on their board. However the frequency increased to almost the maximum frequency(950kHz) when it's power on.
(Vin =27V, Vo=12V, Io=2A, Rfb: R1=8.76kohm, R2=1kohm, Cff=100pF)
However when Vin is…

I have imported the startup model. and…
Part Number: LM3485 Combing through the old buck converter we are currently using and comparing it to the replacement, I fail to see the difference between the two. Can anyone explain to me why this is a new part number?
Old Buck - LM3485MM
