Laser Controller Laser Diode Driver ATLS200MA103

ATLS200MA103 is laser driver with compact size and low noise, which is designed for driving laser diodes. The noise is very low, 2.5µVP-P at 0.1Hz to 10Hz.

This laser driver has many features, i.e., it comes with a high absolute accuracy, <0.1%, and high stability, <100ppm/°C. This laser driver doesn’t need heat sink for heat dissipation, since it generates little heat, <1W. This laser diode driver is packaged in a enclosure which blocks EMIs from outside. Moreover, this laser driver comes with a overheat protection function. When the temperature of the laser driver exceeds 120°C, the driver will shut down itself automatically to prevent the laser driver from being damaged. In order to meet different mounting requirements, this laser driver has two packaging versions, DIP package and SMT package. The former version can be evaluated easily by our evaluation board, ATLS1A103DEV1.0. The physical photo of this laser driver is in below.

Low Noise Laser Diode Driver ATLS500MA104

ATLS500MA104 is a low noise laser diode driver that is designed for driving laser diodes with low noise current of 500mA. The noise is low, 3.96μVP-P at the frequency of 0.1Hz to 10Hz.

The output current of this laser driver can be modulated by an external signal of up to 100 KHz, or set by an input voltage linearly, which results in a minimum 100nS rise and fall times at the output current. When LIS equals to 1V DC plus 200mV AC, the output current is modulated between 200mA to 210mA. The output current and the output current settings can be set separately. The internal temperature of this laser driver can be monitored, once the temperature exceeds 120°C, the laser driver will shut down by itself for avoiding being damaged by over heat. The power supply voltage ranges from 4.75V to 5.75V. There is also a compensation network which keeps the output current to be the same even when the temperature rises.

Low Noise Laser Diode Driver ATLS250MA106

ATLS250MA106 is a constant current laser diode driver with 250mA low noise current. The noise is very low, 2μVP-P at the frequency of 0.1Hz to 10Hz. There is no need for heat sinks.

When the power supply is 5V, the output voltage is from 1.5V to 4V. This laser driver comes with an internal temperature compensation network so as to maintain the output current to be the same even as the laser driver temperature rises. The laser driver will shut down by itself when the temperature exceeds 120°C, which can prevent the laser driver from being damaged by over heat.

There are two packages for the laser driver, DIP package and SMT package. The SMT package laser driver can only be soldered and it’s not convenient to remove it. The DIP package can be removed easily, but the stability of the system is not as good as the SMT package. ATLS250MA106D is for DIP package and ATLS250MA106S is for SMT package. Both DIP and SMT laser drivers are packaged in a 6-sided metal enclosure for avoiding EMIs.
