Part Number: LM25085 Hello TI team :)
Here are my application details:
Vin= 13.8V
Vout= 12.4V
Load= 5A
Inductor= 4.7uH
RT= 249kOhm
Rsns= 10mOhm
Radj= 2kOhm
PFET delay delta= 12ns
I wanted to check for current runaway using equation…
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…
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 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. …
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…
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…
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…
