Hello,
I did not receive comments on the ultrasound images but if the parts have been purchased from TI.com, they have passed final test and follow the datasheet specifications.

Part Number: LM2679 We are only achieving 86% with an input voltage of 24V and an output of 12V. Worse yet, with the same input voltage we get even worse efficiency at 18V, approximately 83%.
Is there a reference design that matches the efficientcy the…
hello, I tried all your tests on my board and TI eval Board. There is a problem with my diode MBRB1060-E3/45. If I use the same eval board diode ( MBRD835L )my board is OK. I will try another diodes to know why there are a problem with my diode.
Part Number: LM2676 Other Parts Discussed in Thread: LM2679 Hi,
We use the LM2676-ADJ for the DC/DC buck from 24VDC to 8VDC, and now, we use the LM2679-ADJ with the same design, but the LM2679 has no output voltage, so please refer to below LM2676-ADJ …
Part Number: LM2679 Hi,
We needed 12v from 24v supply so we are using the constant out LM2679SX-12 but when then inout voltage is slightly increasing let say 25/26 v the outpu is also increaseing from 12to16v can suggest any ideato rectifi
this.

Part Number: LM2679 Hi,
For our internal project we are using LM2679S-3.3/NOPB, LM2679SX-12 buck converters with TO-263 package . There is a center pad in these footprints should we connect it to ground pin of IC or should we keep unconnected?
Part Number: LM2679 Hi,
For our internal project we are using LM2679S-3.3/NOPB buck converter. Kindly review the attached schematics and let me know the comments if any.
Part Number: LM2679 Dear sir,
In LM2679 datasheet, it just list out the rdson data, no Ciss, Coss, Crss of internal DMOS power MOSFET, can you share it with me and customer?
Customer want to use it for Power loss calculation.
Nice day!
Regards,
Jack
Part Number: LM2679 Using LM2679T-12/NOPB, a circuit that outputs 24V input to 12V/5A was constructed. Measuring the output terminal measures 12V. However, when a load of 12V/1A is applied, only about 3V to 4V is output. What's wrong with my circuit?…

Hi Team, seek for some assistance.
LM2679SX-5.0/NOPB and it turns out that we may need to have an enable feature, which this part does not have. However, looking at the block diagram…
