The LDA1-CP2 is an electronic module designed for driving diode lasers (N type) with well controlled and monitored driving current and output laser power.  Its PWM (Pulse Width Modulation) output stage achieves ≥90% high power efficiency, eliminating the need for a heat sink. The output current and laser power can be set linearly by two separate input voltages and monitored linearly at the same time by two output voltages respectively. It comes with a high stability low noise 2.5V reference voltage which can be used for setting the output current and as voltage references for external ADCs and DACs.
