O-Like blu-ray driver problem

[nazca]

just arrived the driver from o-like. connected to diode an 3,7v li battery. a nice smoke exited from the module and no light from diode.
someone got this problem?

i had this problem with the o-like for red.the BR worked fine.

instead of hooking these straight up to a diode... why wouldn't you first do a dummy load?

 

[blue lasers]

i didn't hook it up to the diode.this happend when i was trying to set the current.i attach 4.5 volts and the driver fried up instand.

with or without a load attached ?

Some types of boost drivers fry, if you power them up without a load attached.

 

[jander6442]

^ hence the dummy load.

 

[nazca]

mine fried with diode attached . nothing happened to diode.
thank you o-like. (and he never replyed to my emails)
