Part Number:OPT8241-CDK-EVM
hello
We are going to try test laser module in opt8241 illumination board.
So i modified your reference circuit both QUAD_LASER and HEX LASER like below circuit.
I am wondering several things about below circuits.
1. QUAD_LASER driver
1) I think anode voltage (net : illum_quad_laser) is 5V . that is not enough to operate laser . Because Sum of foword voltage is over 9V. I guess.
2) What is SN74LVC2T45 u13 purpose? only to increase amplitude of TRIG ?. IF TRIG high volage is 5v, we can remove u13?
3) IF i design circuit like this . does it work correctly until 3A (Laser peak current) ? TRIG : freq = 12MHz / duty : 50%
if we should modify else, could you plz some advice?
2. HEX LED DRIVER
1. How much voltage ILLUM_HEX_LED ? ( Boost circuit 's out voltage) How about peak current of led?
2. Why annode(D7) needs voltage (ILLUM_HEX_LED)?
3. IF i design circuit like this . does it work correctly until 3A (Laser peak current) ? TRIG : freq = 12MHz / duty : 50%
if we should modify else, could you plz some advice?
best regards.
