Product description 

LPLDD-1A-16V-3CH Laser Diode Driver is a low current version of a 3 channel RGB lite LPLDD laser 
diode driver. The maximum output current is 1 A per channel. It was designed for lower power laser 
diodes in order to assure smooth waveforms, fast-rising/falling time and low ripple. 

This is the professional three-channel medium-power driver for laser diodes (e.g. RGB laser systems) 
with a built-in soft-start feature. The current of each channel can be independently controlled via the 
analog input of 0 - 5 V with a modulation bandwidth of up to 100 kHz. Each channel has 
a potentiometer that can be used to set the maximum current. 

Each of the controls is labeled on the PCB to make it more intuitive and easier to set. 

The proper connector is attached to the driver for your use. 

This laser controller is provided without a heat sink to allow customers to use their own heatsink. It 
also reduces the price for those customers who wish to operate it at a low current where a heat sink 
is not required. It is a fully functioning component ready to be mounted in laser devices.
