@chipdouglas i answered that question in post # 17 in response to rpaloalto.

talks were not going anywhere i had wanted them to go , at that time.


@ daguin , i can scan it.. ill do it now and post

wow. ok. After seeing that scan, clearly the driver is in fact pre-set, and I do recall pre-setting it. The reason I had originally thought I hadn't set it is that I hadn't marked the set point in my purchase records, but there is no way the driver can have that marking and those solder jumpers and not be pre-set.

So, if the driver was pre-set to 550mA, what happened?

this (FlaminPyro will get a kick out of this):
The MicroBoost driver as stated in the instructions requires a floating diode because the current is sensed on the diode cathode return connection. For high power blu-ray diodes for which it was designed, this is simple because they are all constructed with floating dies. However SirVesa, assuming the connections were the same as the FlexDrive he was used to, and because he didn't look at the directions, soldered it up with a jump wire between the diode cathode and case pin. This has been confirmed via PM with SirVesa. What this error does is return no boost current to the driver for it to sense, and it will keep boosting until its internal current limit is reached.

This mistake is what caused the failure.
 
i soldered the case pin and the neg on the diode together and both to the neg on the driver.

That should still provide the sense data to the driver , no?

So the driver is set correctly and SirVesa installed it like a Micro Flex instead of as a Micro Boost needs to be (NO negative pin soldered to case pin with the micro boost).

Read the manual, Man :tinfoil:

Pure builder's error. The driver is even probably still good, at this juncture.

Peace,

Well ok then that proves im an idiot.


I publicly apologize to your drlava, i should have read the f@#$en manual. (or better yet , understood the floating pin)


You are a stand up guy and very willing to help, and thank you everyone for your objective views and opinions, i hope i didnt waste too much of anyones time.

closing thread...
