my customer is evaluating the LM25085A for a constant current output design .
input: Battery pack voltage 17~29.4V
output voltage :Battery voltage
output current: continuous…
Part Number: LM25085A Hi, Could you tell me about LM25085A gate resistor? Customer is trying to install gate resistor and snubbers to suppress ringing. However,There is no explanation in application note or data sheet. Is it possible to install a gate…
Hi Yusuke-san,
I created a shared public design as an example with your specifications:
https://webench.ti.com/appinfo/webench/scripts/SDP.cgi?ID=CE025DB6A19CFEDD
Fsw=554kHz
D1= STPS20M100SG-TR
M1= Si7149DP
We do not have your customer…
Part Number: LM25085A Hi, Could you tell me about reduced ripple configuration. Is R3,C1,C2 a fixed value in Excel sheet? www.ti.com/.../lm25085aquick-calc
It is different from the calculation formula of datasheet. R3,R2,C2 looks like a fixed value…
Vijay,
It seems that the cause of the problem was the output capacitor ESR. Webench recommended a tantalum capacitor with ESR of 2.5 ohms. This was too high to respond well to a load step transient in our application.
Using a lower ESR capacitor seems…
Other Parts Discussed in Thread: LM25085A The schematic produced from the TI Webench Designer for the LM25085A Switching Regulator is different from its application schematic in the datasheet. Specifically, the Webench Designer schematic has mislabeled…
Other Parts Discussed in Thread: LM25085A
We designed a new project using the LM25085A regulator (as you can see in the image) using the Webench Designer.We designed a circuit with a input voltage range between 22.5V and 25.5V, output of 12V and a maximum…
Hello,
On page 11 of the LM5085A datasheet it shows that by pulling the RT pin to ground, the power supply should shutdown the output. We are using an nFET to pull RT down. The nFET is working and when I turn it on, the line pulls to ground, but the…
Project data ( Buck ) : Vin : 24V Vout : 12V (+-2%) Iout : 5A Guys, for over a week we concentrate our forces to put the project generated by Webench to work. No charge , all wonder Vout = 12V , but with dozens of miliamper load , Vout drops drastically…
