ACS4500BU 4.5A (Buck) Laser Diode Driver

This unit has a slightly smaller profile for easier fit in the hollow back of a 12mm module housing when being used for under 2.5A settings connected directly to the diode pins if that is the goal. Higher currents require heatsinking and then not much difference between this and the 5500 model except this can only do 4.5A and the 5500 can do 5.5A.

ACS4500BU - the next generation of compact buck drivers that came to replace the BlackBuck 3 and BlackBuck 6 ones. Designed to power laser diodes or LEDs from batteries or other power sources.​

Major improvements and differences from BlackBuck 3/6 drivers:

Extended range of output current adjustment
High-side design
Improved soft-start
Ceramic fuse for reverse polarity protection
Larger potentiometer
Thermal areas on the back side for better heat dissipation
