In the case of standard drivers, such a diode should be isolated from the ground of the whole circuit, otherwise the diode will be destroyed. Thanks to that driver, it is not necessary since it connects cathode of a diode directly with minus (GND) of the driver. The current flowing through the diode is regulated by the proper adjustment of the high side voltage supply of the laser diode + (anode). Two potentiometers are used to set the maximum current value and bias current. Due to the fact that the maximum current flowing through the diode depends both on bias current and the analog modulation, using both functions, one should not exceed the current of 2A. Otherwise, the driver may be damaged.Recommendations and requirements The supply voltage should be always higher than or equal to 5V. The minimum supply voltage for other situations is given by the formula: Vin = 0,2* I + Vd Vin is input voltage Vd is diode working voltage I - desired maximum current Modulation input can be used as TTL input with its logic levels of 0V and 5V or as an analog input. 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. We recommend the use of power cables with cross-section of at least 0.35 mm2. Depending on used laser diode, you should monitor and assure proper cooling for the MOSFET transistor. MOSFET should be isolated from the heat sink with silicon pad.Protection The analog input is protected by a 5V1 Zener diode on occasion there appears the voltage higher than 5V. Despite everything, this input should not be used with higher voltages. As this is a miniaturized version of the driver, it does not have reversed polarity protection.
