Part Number: LM2672 Dear all,
I had tested the PDIP version of the LM2672 regulator on a PCB. What a surprise when i decided to try the soic8 package. It has delivered about 11V on a fixed 5V LM2672.
I'm dubtful about that, any suggestions?
Kind…
Hello
Webench does not take into account the lower temperature ranges.
It uses the highest temperature to determine if the thermal limits of the device are not violated.
We have many devices that can support 5V at 2A and 12V at 1A from 22V to 32V.
Are…
Other Parts Discussed in Thread: LM2672 Hi colleagues,
I have a question. I have a card that contains LM2672 simple switcher Regulator. Unfortunately there is a noise on the Vin, so the Vin pin get -4V short time: ~1mikrosecond (at the switch on).
What…
Other Parts Discussed in Thread: LM2672 Hi
My customer uses LM2672 at SYNC pin open. They is making their muss product now.
They have a issue that output voltage has spurious around 10Mhz. (Output voltage has noise)
They connected SYNC pin to GND through…
Hi,
One option would be LM2672 below

Hello
The LM2594 devices are bi-polar and do not require a boot strap capacitor. All of the newer alternatives will require a boot capacitor
and therefore a re-work of the PCB. You might look at the LM2574; it is bi-polar. Otherwise the newer devices…
Hi Shawn,
You can take a look at LM2672. The package and pin out is the same. LM2672 features two more pin functions, SS and SYNC (which are NC for LM2675). If you don't need, you can left them floating.

Suy,
Your schematic shows VDDA connecting the feedback node of the LM25141 through a 0-ohm resistor (sets 3.3VOUT) but it's also connected to the 5V output of the LM2672 through a 0-ohm resistor. This will hinder the regulation. Is this second 0-ohm…
Dear Clemens,
Thanks for the reply.
Sorry, I can not share the schematic due to copyright.
Yes other damaged components are 74LVX125MTC and MC74HC589AD and two IC of CD74HC4538M.
And I checked LM2672 circuit and it is working after removal of these damaged…
