DESCRIPTION

This laser driver is an electronic module designed for

driving diode lasers with up to 2A constant current, high

efficiency, low noise, high reliability, zero EMI, and small

package. Figure 1 shows physical photo of CWD-01-V2-D.

It provides these functions: laser constant current control,

laser current monitoring, over current and thermal protection,

laser current control indication, laser diode status indication,

soft start, and shut down.

It comes with a high stability low noise 2.5V voltage

reference output which can be used for setting the output

current. The reference output can also be used for the ADCs

(Analog to Digital Converters) and/or DACs (Digital to

Analog Converters).

The CWD-01-V2-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.
