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 Dear Expert of Power Design
We are using LM2679 to drive a TEC module, the resistance of the TEC is at the 1-ohm range, but not a consistent number, so we set the output voltage high, in the design is close to 10V. we use the current…
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

Part Number: LM2679 Hi,
For our internal project we are using LM2679SX-12/NOPB buck converter. Kindly review the attached schematics and let me know the comments if any.
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…

Hi all, Just finished the assembly of a few prototype boards and have encountered the following issue. While the circuit correctly outputs 7.4V ± 0.1V while not under load, when a 0…
Part Number: LM2679 Hello,
I am using the LM2679SX-ADJ/NOPB switching regulator in a pcb design and was experiencing a large voltage ripple on the output of the regulator that was about 500 mV pk-pk at ~750 Hz during a <100mA load. This was surprising…
Part Number: LM2679 I made a circuit that converts a 24V input to 12V/5A and tested it. However, when a load is applied, the output voltage drops to 4V. What's wrong with my circuit?
Below is the circuit I made, and I designed the circuit by referring…
Hello Lee,
I am sorry that this took so long. Here are a couple of things that should help:
It appears that the output capacitor is large for this converter. Please remove one of your output capacitors to see if stability is improved.
The…
