Part Number: LM2586LM2586 team,
Can you confirm if the large pad on the TO-263 package is connected to Ground internally? I see this is labelled on the TO-220 package in the datasheet (page 3, section 5), but not on the TO-263 KTW DDPAK.
If not,…
Part Number: LM2586 Hi
Ive been running into some issues getting my IC handle the different kind of load on the secondary side of the transformer, its hard to say if its been the controller loop or the compensation voltage that makes the IC burn out…
Part Number: LM2586 I cannot find any info from TI relating to the recommended paste pattern for this specific 7 pin chip.
I have read this document: Design Summary for 3- and 5-Pin KTT Packages (ti.com) but the LM2586 has a slightly larger pad.
Part Number: LM2586 Hi,
I want to generate from a 24V input, a dual power supply, +-15V, with a maximum current of 0,2A on both output.
I have to use a flyback design so I choosed the LM2586 as controller for the transformer.
My question is: have…
Chuchen,
I would recommend that the customer simulate this in WEBENCH. Spice sims are already built into the tool. If you have further questions, please feel free to reach out to me directly.
Thanks,
Hi Rohat,
Have you got the waveform of SW?
LM2586 has a current limit of 4A. The rated current of the chosen inductor is 1.1A. But if the input voltage is 24V, the average input current could not reach to 1A. Please use multimeter and current probe…
Part Number: LM2586 Tool/software: WEBENCH® Design Tools When exporting a design to Autocad Eagle, what is the proper order of importing to reduce errors. Also, I am new to Eagle; what do I do with the XML file that is generated?
If it is damaged after a while it may be overheating. You may need more heat sink.
You could try to temporaritly use the T package with a heat sink and see if it survives.
The only other thing could be a spike on the SW pin. Can you use a fast scope…
Other Parts Discussed in Thread: LM2586 , LM2577 I would like to generate 70-145VDC using the LM2586 adj and a 1:10 transformer. The transformer is a Midcom WE 750032050 that is used for Linear Tech capacitor charge circuits. Has anyone ever used the…
