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…
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…
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 Other Parts Discussed in Thread: LM2576 Hello, The circuit is built with LM2679SX-5.0, but when there is no load, the voltage gradually rises from the start of the power supply to about 9V. When a load is connected, the voltage drops…
Part Number: LM2679 I'm using the LM2679 in an inverting buck-boost topology as shown in AN-1157 and this related app note . The note is easy to follow along, but I have a question about the output voltage limitations.
I'm using a positive 13.8 voltage…
Part Number: LM2679 Case No.: CS0637854 Short description: Circuit design is not delivering output voltage expected. Case details or comments:
I am working with a PCB consultant, and we are having issues getting (what we consider a relatively simple…
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…

Hi,
I am probably going to use LM2679SX-ADJ/NOPB regulator for my 7V project. Since i want to use TO-263 version, my only question which is not answered in the datesheet is where do i connect the TAB of this package? In datasheet…
Part Number: LM2679 Hi Team,
This is customer request and i would be very happy if you can support:
My customer currently working on EE: CNC control and they need support on DC/DC power supply.
The question is they used Webench for this design decided…
