4A SXD Super X-Drive Laser Driver - NDB7A75 - NUBM44 - NUBM07E

Description

Listing is for a single SXD Super X-Drive Bucking Laser Driver preset to 4A. The Sueper X-Drive is an extremely efficient buck style regulator with many built in safety features to protect and give long life to your laser diodes. Driver has soft start, overshoot protection and very low noise. The driver can operate without an external heat sink with the current up to 1.5A , but it requires a heat sink for currents above 1.5A if you want continuous operation.
It works with 2 or 3 cells Li-Ion or 6.5V-12V DC PSU.
Warning do not use 2S or 3S Lipo packs. Being designed for extremely high instant demant current applications.  When connecting to lower current draw loads compared to its potential that transients well past what the input shunt can protect the IC from can be generated. They will damage the driver. Use Li-ion cells if you are looking to power via batteries.
Don't power the driver without a load connected like connecting the driver directly to a DMM. The laser driver should be connected to the driver with a soldered and secure connection without anything else in series on the output of the driver. A quick connect can be used on the input side of the driver but a secure permanent connection should be used between the driver and diode.
Here are a some pictures of the dimensions:
SXD Super X-Drive TTL control. These instructions are only if you plan to use TTL to control the driver. If you don't plan on using TTL the driver will work as is no need to modify anything.:) PWN/TTL Modulation Frequency: Up to 1kHz  Modulation Voltage 0-5V Full range: 1.6V ON "Max 12V" & 0.6V - 0V OFF
Solder the modulation Wire to the Yellow Arrow after removing the 10K.^^^^ Like SO:
​ Enable Pin is High "ON" Minimum 1.6V with an Ultimate MAX of 12V input Enable Pin is Low "OFF"  0.6V or lower 12V MAX the enable pin can take.
Remove the Ramp Up Capacitor.
