As shown in Figure 1, TECA1-5V-2.5V-Dis a typical Peltier controller of ATI (Analog Technologies, Inc.). This Peltier controller has an input voltage of 5V and the maximum output voltage of 2.5V. And the Peltier controller is packaged in a metal enclosure, which helps to block the interferences between the controller and other electronics.(more)
In optical fiber communication, optical module function is very important, and laser driver is used for light emission front, which can realize laser bias and modulation. The laser controller converts the voltage signal into current signal with high speed to modulatelaser and generate high-speed light signal. And then the light signal is coupled to the optical fiber transmission.(more)
In recent years, high precision semiconductor laser with continuous adjustable high stability is more and more widely used in military and civilian fields. And the demand of driving power supply used with laser is also becoming more and more. The semiconductor laser driving power supply with excellent quality and high stability and high precision should ensure the laser work safely, anti-interference ability is strong and the laser has the normal service life.(more)
TEC controller is a kind of semiconductor device, which realize the refrigerating and heatingprocess according to the current trend through the TEC.And our TEC controllers are also based on TEC current direction and strength to realize temperature control. By using the TEC controller, we can precisely adjust the temperature of the object. And it has the advantages of high efficiency, high stability, high reliability and small size.(more)
DC-DC converter is a voltage converter that changes input voltageinto output fixed voltage. The DC-DC converter can be divided into three categories: step-up DC-DC converter step-down DC-DC converter and step-up and step-down converter. According to the demand, there are three types of control to choose:PWM with high efficiency has good output voltage ripple and noise; even after long time use, PFM has the advantages of small power consumption, especially when the load is small; PWM/PFM can achieve the control of small load and heavy load.At present, DC-DC converters are widely used in mobile phone, MP3, digital cameras, portable media players and other products.The following introduce is about the principle of DC-DC and design skills.(more)
With the development of science and technology, thermal electric coolers (TECs) have become more and more popular in cooling systems. TECs can both heat and cool at the same time, depending on the direction of the input current. And TECs have many advantages of no pollution, no noise, no wearing, a long life time, and high reliability, etc.(more)
ATH100K1R25 series ntc thermistors are high precision glass encapsulated thermistors with long term stability. Comparing with conventional epoxy encapsulated thermistors, ATH100K1R25 has a wider temperature range, especially on the high end applications, better long term stability, smaller size, and a shorter response time. Besides the bare leads, we provide two insulation versions. One is with the two leads covered by plastic tubing, and the part number is ATH100K1R25T70, and the other one, the ATH100K1R25T70S, is sealed between the thermistor head and the plastic tubing. All of the thermistors can work under up to 140°C temperature and the latter is liquid resistant. The main parameters are shown in the table below.(more)
ATI designs and manufactures a wide range of analog electronic products for the laser and industries. These products serve applications in medical, military, scientific, and industrial markets. ATI offers a line of diode drivers both high current and constant current applications.(more)
The ATH100K1R25 is a high precision and glass encapsulated NTC thermistor with high stability. This NTC thermistor can be applied for temperature sensing for laser diodes, optical components, temperature control system, industrial process control, etc. All these applications require high temperature sensitivity, long term stability, and/or high sensing temperature.(more)
