Lite drivers

0-5A Lite LPLDD v2

New version of primary driver for almost every laser diode with adjustable maximum current in the range 0 to 5 A. The control input allows for the modulation of the current flowing through the diode at a rate of up to 100 kHz.

New version of classic laser diode driver:

Added LED diode showing that driver is connected.
Added softstart to protect againts switch-on effects
Added labels on the board - more intuitive and easier to set
Smaller size - only 15mm x 30mm and capable of driving 5A!

Added large surface of copper which cools the sense resistor.

Basic driver for powering laser diodes with the option to adjust maximum output current in the range of 0-5 A, and to modulate the current flowing through the diode with frequency up to 100kHz.

 

A test with the 100kHz square-wave input signal modulation is shown below.

 

Test done using:

6W NUBM44 laser diode

15cm long 0.35mm2 wires

12V input voltage

80x80x20 heatsink on power mosfet



Since it is lite version of the driver it does not have protection against polarity change. Be sure you connect it acordingly to the labels on the PCB.

By selecting an appropriate PSU the driver in question, it is possible to power literally every laser diode available on the market up to 5W - 405 nm, 445 nm, 520 nm, 638 nm, 650 nm, 808 nm, 980 nm.
The examples of diodses are: 1 W 445 nm, 3,5 W 445 nm, 700 mW 635 nm, 200 mW 808 nm, 1 W 808 nm, 5 W 808 nm, 1W 520nm.

Recommendations and requirements

The supply voltage should be always higher than or equal to 3,3V. 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 and PSU, you should monitor and assure proper cooling for the MOSFET transistor. The MOSFET/MOSFETS must be isolated from the heatsink/plate with silicon pad as well as plastic sleeve. Short circuit between MOSFET and heatsink/plate can damage the driver and can be dangerous for the Laser Diode.


Protection

Modulation input of the driver is protected by 5V1 Zener diode. Nevertheless, one should not use modulation voltage higher than 5V. Shottky diode is being used for ESD protection.

The output of the driver is protected by shottky diode which doesn't allow the reverse voltage to appear.
