Hi Marc,
The key capacitor is C67 - this should be placed closed to the FET to minimize the switching loop area comprising the FET, diode and sense resistor. The lower parasitic inductance improves the performance of the circuit, allowing reduction…
Part Number: LM25088 Other Parts Discussed in Thread: LM5088 I created two versions of a large PCB, both with a[26V down to 15V]-12V DC-DC up to >5A output current based on the same LM25088 schematic but different layouts. Both times I had issues with…
Part Number: LM25088-5088QUICK-CALC Would you let me know about password of LM25088-5088QUICK-CALC?
I want to confirm customer's value for compensation network on this tool.

Part Number: LM25088 Our customers have always used lm25088mh-1 to produce their products before. Recently, 1000 pcs products have been replaced by lm25088qmh-2. Other circuits have not been changed. It is found that 300 + PCs are burned out. What are…
Part Number: LM25088
Hello,
With the LM25088, there are 2 versions. The LM25088-1 offers dithering, and the LM25088-2 offers overload restart timing. They use the same pin for these two different purposes.
For production, we're considering using…
Part Number: LM25088 I do have a LM25088 design that is to run on VIN = 26V, VOUT=24V, I_MAX=10A. The controller works excellent when the load is fine. However my spec requires my design to run at no load. So I already added some base load using resistors…
Part Number: LM25088 Hi, I'm trying to calculate where the DC Modulators low frequency pole is located in my design. I thought tthe calculation for this was
1/Rload*Cout
For a transconductance converter.
However in the datasheets design example…
Part Number: LM25088 Other Parts Discussed in Thread: LM5088 Hello,
Is it possible to utilize the SS pin of LM25088/LM5088 for longer soft-start times than what Webench allows?
Webench has a field for entering a millisecond value, but if we enter…
Part Number: LM25088 Hello!
I got unexpected problem. LM25088 works normaly for a while, but after one day it did not work properly if Vin reaches 17V Vfb can't be normalized to 1.205V, under 17V it's working properly. Any ideas? Thanks.
