Part Number: LM25085 Tool/software: Hi TI Team
am using the TI available PSPICE model of the LM25085, the issue is the voltage at the RT pin does not follow the data sheet, i placed a 243K resistor in the PSPICE simulation, but its measuring 1.16V where…
Part Number: LM25085 Tool/software: Hi,
1. What are the maximum and minimum values of IPGATE (Driver Output Sink Current)?
2. What are the maximum and minimum values of RPGATE (Driver Output Resistance)? Am I correct in understanding that the maximum…
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?

Part Number: LM25085 Tool/software: Hi
I designed a Step Dawn power supply based on the typical application of the LM25085 .
In my application noise is not an issue, nor current limiting, so is the simplest possible design.
That said it required…
Part Number: LM25085 Other Parts Discussed in Thread: LM61460-Q1 Tool/software: Hello guys,
One of my customers want to design a variable output voltage power supply using LM25085 for their new products.
They have the following question at this moment…
Part Number: LM25085
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 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…
Part Number: LM25085 Hi expert,
Customer find that when output current increase from 0 to 400mA, the output voltage increases nearly 1V. Could you please give some suggestions? Thanks.
