Diode burned! Please help.

[esg1]

I Drive to Micro Micro Boost and ran diode. I've worked with 3.7 volts. But the output is 13 volts. Voltage is not adjusted. Diode burned.

Wow can you give more detailed information, from what you said all I can tell you is it sounds like something isn't right

 

[Firefly]

c..p, how the output give 13 volt?

Umm, please explain properly.

What diode is it first of all ?

How did you set the current (if you did) ?
How is it wired ?

Is set to 750ma. I measured out and read 13 volts.

Can we get a picture of the other side please.

Does it output anything at all ? A faint light atleast ?

You should try the driver with a testload to see if driver is fried or not.

Going by the awfully limited information that you have provided, are you sure that the diode has "burned" as per se?
Now, I dont use the microboost, but I believe that its a boost driver hence the name, and it will boost the voltage to higher and higher voltages to the LD until it reaches the set current value that you have set the driver too.
It may be possible that the circuit too your diode is actually open due to poor soldering, thus you are measureing 13 volts output.
It is also possible that you connected your diode to a live powered driver? This is NOT to be done, as the output voltage of a boost driver with no load will be very high, say 13 volts, and would kill a diode immediately.
You need to connect the LD and THEN power the driver.
These are only guesses, based on limited information. You need to provide more information if you want any more help.

It works ok. Absence of contact diode has been corrupted. I've learned it. Thank you for responding.
