Dear all,
Did someone use this driver in picture attached?
It is marked to be booster for blue diodes which support 3.7-4V2 input and 3A output. I am really in doubt that this driver will support 3Amps on output which is meaning at least 12w for blue diodes...
I've did some tests using a dummy driver + UIN = 4V (power bench supply)
- connecting at output a dummy driver (4 x 1N4X diodes ), output current is ~2A and output voltage across diodes around 4V.
- if I'm increasing number of dummy diodes, for 5 x 1N4X, I am getting Iout ~1,25A and for 6 x 1Nx I am getting Iout = 0.4A and Uout is decreasing somewhere around 2V...
Did someone used it successfully? If yes, what is the value of regulated current output when connected on blue diodes?
Regards,
Alx
