Part Number: LM25085 Tool/software: WEBENCH® Design Tools We are considering adopting your company's LM25085 for new projects.
We have used your company's WEBENCH under the conditions of Vin = 24V, Vout = Max18.1V, Typ10.5V, Iout = Max10A, Typ4.2A.…
Part Number: LM25085 Hello,
We have a device that needs to be re-designed. It uses an LM25085 buck converter. The voltage to the converter is sourced from a nearby lithium ion battery pack. The spec states that the input capacitors(C9 and C13) are necessary…
Part Number: LM25085 Other Parts Discussed in Thread: LM3102 , LM25011 , LM3100 Hi, I have an urgent issue about the LM25085:
Circuit Description: LM25085, as the first-stage Buck chip, is connected to the supercapacitor through the MOS driven by the…
Part Number: LM25085 Other Parts Discussed in Thread: LMR12010 Hi team,
I have saw AN-2157, "Constant Current Constant Voltage Buck Converter With LM25085, or, Implementing Accurate Current Limit With LM25085", seems good example for design CC/CV. …
Hi,
What's the heaviest load the circuit can deliver? Could you please probe switching voltage and inductor current waveforms under normal and abnormal conditions? Thanks.
Part Number: LM25085 Hi,
We designed custom buck converter (LM25085) using web bench for
input voltage = 10.1 V to 12.6V
output voltage = 9.8V
current output = 8A
Resistive load =1.8 to 2 ohm
output voltage when
load is connected = 3…
Part Number: LM25085 Other Parts Discussed in Thread: LMR50410 , LMR36510 , Hi,
I am a big fan of Webench and have used it for many SMPS designs. My latest design however, utilising the LM25085 seems to have some issues.
Setting Vin to 15 - 36V, Vout…
Part Number: LM25085 Hello Guys,
Good day.
Our customer is trying to export his webench design in Cadence OrCAD but keeps on encountering export-failed error. I tried it myself but encountered the same error. Is it possible to provide him the Orcad…
Part Number: LM25085 Hello,
I'm trying to design a 4.2V regulator using the LM25085. I have run a few webench-design based "startup" simulations and, in each case, the simulation shows a significant output voltage overshoot at the very beginning of…
Qun,
The LM25085 is a buck controller. This means the maximum output current is dependent on the current capability of the FET and the LM25085's ability to drive the FET. The drive strength of the LM25085 is strong enough to conservatively drive a FET…
