Introducing the ALTAIR05T-800TR from STMicroelectronics

The ALTAIR05T-800TR is a state-of-the-art power switch designed by STMicroelectronics, a leader in semiconductor solutions. This advanced product is part of the ALTAIR family of high-voltage converters, which are renowned for their efficiency and reliability in a wide range of applications.

At the core of the ALTAIR05T-800TR is an 800 V rugged power MOSFET combined with a PWM controller. This integration enables the device to deliver exceptional performance in offline power supplies. The MOSFET's high voltage capability ensures that it can withstand voltage spikes and surges, which are common in fluctuating power environments, making it ideal for use in areas with unstable mains voltage.

The device is optimized for quasi-resonant flyback converters, which is a preferred topology for designers looking to achieve high efficiency. The quasi-resonant operation reduces electromagnetic interference (EMI) and improves overall efficiency, which is crucial for meeting energy-saving standards and regulations. This makes the ALTAIR05T-800TR an excellent choice for eco-conscious designs, such as energy-efficient adapters and chargers, LED lighting, and auxiliary power supplies.

Another standout feature of the ALTAIR05T-800TR is its built-in protection systems. The device includes overvoltage protection (OVP), overcurrent protection (OCP), and a thermal shutdown feature. These protections not only safeguard the power switch itself but also extend the lifetime and reliability of the end product. In addition, the device is designed with burst-mode operation, which significantly reduces power consumption at light load, further enhancing its energy-saving capabilities.

The ALTAIR05T-800TR comes in a compact and robust package, making it suitable for space-constrained applications. Its Tape and Reel (TR) packaging option facilitates automated assembly processes, ensuring efficient manufacturing and scalability for high-volume production.

In summary, the ALTAIR05T-800TR from STMicroelectronics represents a blend of high-voltage robustness, energy efficiency, and integrated protection features, making it a top choice for designers and manufacturers looking to create reliable and eco-friendly power solutions.
