Integrated laser drivers is recommended for fast switching, since signal changes will move faster because of reduced wiring line inductance and capacitance. The use of integrated laser driver circuit gives some benefit such as: output power stability improvement, board space reduction, error monitoring, better dynamic performance, and MTBF reliability improvement. [...]

By controlling the size of the resistor in one of the four filters the frequency could be adjusted. In order to get the correct size signal, the we must use a potentiometer to be placed to the one of the resistors while also measuring oscilloscope’s output. This will be used to know what size of resistor should be worked at 60Hz. [...]

NCP1034 known to be high voltage, high power and high efficiency buck converter. A voltage mode PWM controller for a high synchronous buck. According to the datasheet, this buck converter features low output voltage ripple, ceramic capacitors, over current protection, and under voltage protection. [...]
