DESCRIPTION

There are two versions: the LDA1-CP1-D-SNI and the

LDA1-CP1-D-SNO. The former one represents that the

external signal synchronizes the signal of the chip, and the

latter one is that the signal of the chip synchronizes the

external signal.

The LDA1-CP1-D is an electronic module designed for

driving diode lasers (P 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.

LDA1-CP1-D is packaged in a 6 sided metal enclosure,

which blocks EMIs (Electro-Magnetic Interferences) to

prevent the controller and other electronics from interfering

each other.

The LDA1-CP1-D physical photo is shown in Figure 1.

Figure 2 is the actual size top view of the LDA1-CP1-D,

which shows the pin names and locations. Its thickness is

4.6mm. The LDA1-CP1-D pin functions are shown in table 1.
