TEA1750T/N1 - GreenChip SMPS Control IC by NXP

The TEA1750T/N1 is a versatile and highly integrated circuit designed by NXP Semiconductors, tailored for Switched Mode Power Supply (SMPS) applications. This innovative control IC is part of NXP's acclaimed GreenChip line of products, which are renowned for their energy efficiency and reduced ecological footprint. The TEA1750T/N1 combines several features that make it suitable for a wide range of power supply systems, such as adapters, LCD monitors, and TVs.

At the core of the TEA1750T/N1 is a combination of a PFC (Power Factor Correction) controller and an LLC resonant half-bridge controller. This integration allows for a cost-effective and power-efficient solution for creating a dual-stage power conversion system. The PFC controller ensures that the power supply conforms to international regulations by correcting the power factor, thereby reducing reactive power and improving the overall efficiency of the electrical system.

The LLC resonant controller, on the other hand, offers zero-voltage switching (ZVS), which minimizes switching losses and enhances the efficiency of the power conversion process. This feature is particularly important for achieving high efficiency in power supplies operating at various load conditions.

The TEA1750T/N1 also boasts an integrated high-voltage level shifter, which simplifies the circuit design by eliminating the need for additional components. The IC's brownout protection ensures reliable operation during under-voltage conditions, safeguarding the power supply and the devices it powers. Furthermore, the TEA1750T/N1 includes protections against overvoltage, overcurrent, and overtemperature, making it a robust choice for critical applications.

NXP's TEA1750T/N1 operates in a wide supply voltage range and is available in a compact SO16 package, making it easy to integrate into various designs with limited space. Its versatility and integration of multiple control functions make it an excellent choice for designers looking to create efficient, reliable, and compact power supplies while adhering to environmental standards.
