Part Number: LM25085 Tool/software: Hi Expert,
I found the content in datasheet said the value of Rfb typically lower than 20kOHM as below picture:
Does the value of Rfb1 and Rfb2 have potential negative impact if they are larger than 20kOHM?

Hi Ridge,
Thank you very much for your reply and I'm sorry to be late my reply.
I recommended them to consider using the device.
Thank you again and best regards, Kazuya.
Hi I want to thank you for your effort helping me to solve this issue, however I must inform you that I finally solve it by replacing the device with an other from your competition on the far east (after a small PCB layout change) I always prefer to select…
Part Number: LM25085 Other Parts Discussed in Thread: LM61460 Hi all,
I am having issues with a power supply design using the LM25085.
Specs:
- input voltage 24 V
- output voltage 5 V
- output current 0.6 - 5 A
Heat dissipation is 20% at 1 amp, 40% at…

Hello,
We need your advice for selecting a High side switch buck converter ic with similar functional as LM25085.
Requirements are: vin 8 to 20v+-, Vout 6v, 4A and lowest frequency posiible.
Thank you in advance
Part Number: LM25085 Dear members,
we have used LM25085 to control a FAN by changing the duty cycle. I want that this circuit limits the current at 4A. Input voltage will be 0 to 12V according to duty cycle.
Rsense= 0.030 ohm. Having 30mOhm I observed…
Part Number: LM25085-Q1 Hi, I have a question about the switching frequency of LM25085-Q1,
LM25085-Q encounters the phenomenon that the frequency cannot be adjusted by changing Rt during use. The maximum input range is 11-16V, and the output range is…
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 LM74701…
Part Number: LM25085
Hi, we make a buck controller topology in which USB PD input. This means input voltages are 5V, 9V, 15V, and 20V. The maximum current is 5A. We want, if the input voltage is 5V, İnput voltage will directly pass to the output. In…

HEllo,
I'm designing a dynamic Li-ion charger. The user will set the precharging current, the cuttoff voltage, the CC current, the CV threshold and the CV voltage depending on the bateery specs.
for that reason, i have added…
