Thank you very much Keith,
I have made one driver circuit by using " iCHB QFN 24" driver from iC haus. But during my testing 2-3 diodes are failed. So i"m bit worried about the reliabilty of my circuit. I have one optical power meter and i"m setting up the power below the maximum level(80%) also.
Hi,
Can any one help me to make a good laser diode driver or is there any good IC which can drive laser diodes.
We have laser diodes with 200 mW power and 450mA operating current.
I have read that Constant current drivers are the best drivers to drive laser diodes,is that true?
Thanks in...
Re: Floating Ground SMPS
Thank you embedsys,
The DC voltages are tested with respect to DC ground (between +,- terminals)using multimeter in DC mode and volatges are perfect.
The volatge i was talking about is " AC voltage",with respect to chasis ground(Earth) and output terminals(+.-)
Hello,
We have got one Dual output SMPS from a vendor. It has three input terminals (L-line,N-neutral,E-Earth ).The earth terminal is connected to the chasis (metalic enclosure) of the SMPS alone. He has not used this anywhre in the circuit part.
We have tested the power supply and found...
Hello,
For my upcoming project i need to communicate between two microcontrollers( 8bit LPC controlller from NXP) sitting in two different boards.The distance between the two board is minum of 2meters.
Initially "controller1" will communicate with "controller2" and give command to start...
