[1] Logic supply should be in range 7.5V – 35V
Power Supply
When you are powering both the laser diode and the driver from one power supply in the range of 7.5 - 35V DC the LD VCC jumper should be connected.
In the case of powering a diode with low voltage , i.e 3 V, one should use two power supplies and the VLD jumper should be disconnected.
The driver has to be powered with voltage in the range of 7.5 - 35 V DC and laser diode has to be connected to the power supply in the range of 3.3 V - 35 V DC
This feature allows you to power your laser diode from low voltage, therefore, lower power dissipation produced by the driver.
Modulation Inputs
Modulation inputs accepts 0-5V signals
Analog modulation means that by using 2.5 V on ANG input you get 50% output power, analogically by using 4 V you get 80% output power, etc.
Toggling input can be used as PWM. This means that using duty cycle 50 % you get 50% output power.
Modulation input of the driver is protected by a 5V1 Zener diode. Nevertheless, one should not use a modulation voltage higher than 5 V.
Thermal protection
Driver has a thermal protection system that protects the laser diode from overheating.
Thermal protection system is designed to work with NTC 10kΩ, β=3950 thermistor.
Temperature at which the protection operates can be set in range 10 - 50 oC using a trimmer.
Exemplary Test
The test was done using:
- LPLDD-5A-35V-TP driver
- 6 W silicon diode (at 5A )
- diode soldered directly to driver
- 4 V input voltage (10kHz @ 5% duty cycle)
