1. IDRV3 V1 High Power Laser Diode Driver User s Manual revision 3 May 2013 Thank you for purchasing the iDRV3 V1 CONSTANT CURRENT BUCK laser diode LED driver Specs Max output current 3A Input voltage 3 6V to 16V upgradable to 25V with higher rated capacitors Low Current Ripple lt 10mA Overvoltage protection at the output same voltage as input with no current Overcurrent protection Load disconnected protection Over temperature protection 150 C at the junction Short Circuit Protection Reverse polarity at the output PCB Size 18 70mm x 12mm Driver s bottom must be used as a heatsink base Apply a thin layer of thermal paste thermal silicone and attach it to aluminum copper heatsink for cooling I WARNING DO NOT REVERSE THE POLARITY OF THE INPUT THIS WILL RESULT IN IMMEDIATE DAMAGE TO THE IC WITHOUT ANY CHANCE OF RECOVERING UNLESS THE IC IS REPLACED I I IMPORTANT Input Output Leads must be able to carry the current passing through them without overheating and causing resistance Good and flexible leads such as Silicon Wires are recommended See picture for the correct way of connecting before using I I IMPORTANT Discharge the output capacitors of the driver before connecting the laser diode to the corresponding output leads Failing to do so will most likely shoot a huge spike in your laser diode and instantaneously cause damage to it I I IMPORTANT Input ground and Out2. ername foulmist
3. put Ground are not continuous Do not use with case positive or case negative diodes unless they are isolated from the host body and power source ground Output current is preset at the time of purchase and should be tampered with only by an experienced user with good soldering skills and appropriate resistors 0805 package Be sure to use a test load before putting the driver into your final project The yellow mark shows the place of the sense resistors 0805 size package resistors is required Optionally two or more resistors can be stacked on each other if you don t have the correct value Maximum current is 3A with a 0 0839 sense resistor If you decide to change the resistor do that at your own risk Output current formula I 0 25 R The driver features a soft start and no current spikes overshoots Output ripple is kept at max 10mA Disclaimer The iDRV 3 is assembled and tested on oscilloscope prior to shipping to ensure a perfect working condition don t take responsibility for improper handling reverse polarity not heatsinking short circuiting operating the driver outside it s specs tampering with the Rset resistor or any other components or any other USER fault causing damage to the driver or your application Before using the driver in your final project always use a test dummy load for testing Contact Info Skype foulmist Email foulmist abv bg Laserpointerforums com us
