Part Number: LM25085A Tool/software: Hi,
I wanted to use this part for CC-CV converting. I used same schematic config as in datasheet (my schematic below) but IC seems not to be active. As if it is in shutdown mode. When I measure gate pin of PFET with…
Part Number: LM25085A I'm using the LM25085A Buck Controller to try to convert 29V to 12V with a max load of 8A. After testing with a multimeter, my issue is that VOUT is the same as VIN (29V). Is this a common issue and what could be the solution? I…

I am using the LM25085A buck converter to regulate a 24-30V input (29V nominal) to a 12V output with a max load of 8A. I put my design requirements into the WEBENCH online tool and selected…
Part Number: LM25085A Hello,
I would like to ask you a question about the LM25085A device. The figure below shows the switching behavior when VIN is changed. Set RT=330kΩ. It looks like normal switching at VIN=17V. At VIN=14.9V, switching may turn off…
Part Number: LM25085A Other Parts Discussed in Thread: LM25085 , LM5085 Hi,
I designed in this chip to convert 18V to 12V at 8A. I used power designer which provided me with a feedback network of 10K and 806Ohms as shown.
If I used the equation…
Part Number: LM25085A Other Parts Discussed in Thread: LM61495 , Hi,
I would like some help to determine the issue I am finding at the output voltage for the +6V@6A power supply (U201 of the "IO Board REV01 - PG2.pdf" file).
Basically, everything…
Part Number: LM25085A Other Parts Discussed in Thread: COT Hello,
I followed the recommendations from WEBENCH Power Designer to create a 24V to 12V / 4A regulator with the LM25085A. But on my now produces boards is the regulator works not as designed…
