In order to meet customer demand for drving high voltage laser diode, we have developed a series of high voltage constant current laser drivers ATLSXA216. There are three models with three different current. It has both a wide input voltage range from 5.5V to 15V and a wide output voltage range from 0.8V to 0.8VVPS. At the same time, it allows driving one or more laser diodes and its current can be as high as 12A. There is no need for heat sink with high efficiency. Its very difficult to meet th...(more)
Evaluation board TECEV104 for TEC controllers is designed to evaluate the functions and basic specifications of TEC controllers. The series TEC controller includes TECA1XVXV-D, TECA1XVXV-DAH, TEC5V4A-D and TEC5V6A-D. The evaluation board is mainly used to adjust the TEC controllers external compensation network to match the users thermal load characteristics. There are solder pads on the left and right edges of the board that can be used for connecting the external instruments. The evaluation bo...(more)
The TEC Controller TEC5V4A is designed for driving TECs. It can be highly stable to adjust the object temperature. There are three versions for this controller: TEC5V4A-D, TEC5V4A-DA, TEC5V4A-DAH. It has a very small package with a 6 sided metal enclosure to prevent the controller and other electronics from interfering with each other. The TEC5V4A has high efficiency without using a heat sink. The efficiency is up to 90%. It is powered by a DC voltage 5V and the output current can go up to 4A. T...(more)
Our main products include tec controllers, laser drivers, tec module, thermistors, high voltage power supply and so on. Today I will introduce a low noise constant current laser driver ATLSXXX104. There are 5 models: ATLS100MA104, ATLS250MA104, ATLS500MA104, ATLS1A104 and ATLS1.5A104. The ATLSXXX104 series laser drivers have ultra low output noise, compact size, current-limited protection, and two kinds of packaging are available: DIP and SMT. If the controller temperature exceeds the preset lim...(more)
Laser diodes are the most common laser type in the market, which can be used in telecommunication, measuring instruments, barcode readers, laser absorption spectrometry, and many other applications. This product, ATLS100MA103, is a laser driver that is designed for driving these laser diodes with ultra-low noise and constant current. The output current noise is as low as 1.5uAP-P when the frequency is 0.1Hz to 10Hz, and the output current is 100mA. This laser driver does not require a heat sink...(more)
Evaluation board for ATLSXA201D series diode laser drivers is designed to evaluate the functions and basic specifications for ATLSXA201D, The series includes ATLS500MA201D, ATLS1A201D, ATLS2A201D, ATLS3A201D, ATLS4A201D, and ATLS6A201D. The evaluation board has many good features. It can set and monitor the output current, has an LED for indicating the working status of the driver, and so on. Multiple solder pads on the edges of the board can be used for connecting the external instruments or co...(more)
As a special cold source, TEC module has the following advantages and characteristics: no need for any refrigerant, continuous working, no pollution, no rotating parts or rotating effect. It is a solid device without sliding parts, or vibration and noise during operation, long life, easy to install. TEC module has two functions: cooling and heating. The cooling efficiency is generally not high, but the heating efficiency is high, always greater than 1. Therefore, a single device can replace disc...(more)
Thermistor is a type of sensitive components, which can be divided into positive temperature coefficient thermistor (PTC) and negative temperature coefficient thermistor (NTC) according to different temperature coefficient. Thermistors are typically temperature sensitive and exhibit different resistance values at different temperatures. For positive temperature coefficient thermistor, the higher the temperature, the greater the resistance. For negative temperature coefficient thermistor, t...(more)
