Tool/software:
Dear TI,
I am using LMG1020 EVAL KIT to drive a laser diode capable of 15W optical power.
- Diode Laser voltage 13V-20V
- Current up to 5A
- Signal generator connected directly to IN+, Pulse waveform 20ns, 50Khz frequency, Duty cycle 0.1%
I want to get the total power from the diode and I cannot change the duty cycle because this will damage the diode in the end, the actual current is <1mA at 0.1% , all the signals are looking fine : gate,K, IN+, but the current is very low.
Please support!
Regards,
Abel
