NXP TEA2016AAT Digital Controller For High-Efficiency Resonant Power Supply

As a professional electronic component supplier, Shenzhen Mingjiaoda Electronics Co., Ltd. has been providing customers with high-quality electronic device solutions for a long time, including the NXP TEA2016AAT digitally configurable LLC and PFC combo controller. Designed for high-efficiency resonant power supplies, this advanced controller integrates the LLC resonant converter and power factor correction (PFC) functions in a single chip in a compact SO16 package, providing an efficient and reliable solution for power systems in the 90W to 500W power range.

Product Overview and Technical Features：

TEA2016AAT is a digital, configurable LLC and PFC combo controller for high-efficiency resonant power supplies. Our product includes both the LLC controller functionality and PFC controller, which operates in DCM and QR mode.

TEA2016AAT comes in a low profile and narrow body-width SO16 package. Our sleek design enables consumers to build a complete resonant power supply with few components, simplifying the design process.

Combining the TEA2016AAT with our TEA1995T gives consumers an easy-to-design, highly efficient, and reliable power supply that provides 90 W to 500 W with minimal external components. The system provides low, no-load input power (< 75 mW; total system including the TEA2016AAT/TEA1995T combination) and high efficiency from minimum to maximum load.

This power supply meets the efficiency regulations of Energy Star, the Department of Energy, the Eco-design directive of the European Union, the European Code of Conduct, and other energy regulations. Because the TEA2016AAT is so efficient, there is no need for any auxiliary low-power supply.

Key technical features include:

High-efficiency operation modes: The TEA2016AAT supports Discontinuous Conduction Mode (DCM) and Quasi-Resonant (QR) mode operation for high efficiency over the full load range

Wide operating range: The TEA2016AAT is suitable for power applications ranging from 90W to 500W, meeting the needs of a wide range of applications from consumer electronics to industrial equipment.

Low standby power consumption: The TEA2016AAT, when used with the TEA1995T synchronous rectifier controller, provides a no-load input power of less than 75mW.

Integrated high-voltage start-up: The TEA2016AAT has a built-in high-voltage start-up circuit, reducing the number of external components.

Comprehensive Protection: The TEA2016AAT offers over a dozen protection mechanisms for overvoltage, overcurrent, overheating, inrush current, etc., each of which can be independently configured to latch, safe restart, or lockout mode after multiple attempts.

Performance Advantages and Energy Efficiency

The TEA2016AAT represents the current state-of-the-art in resonant power control technology, and its superior efficiency performance makes it the choice for meeting the world's most stringent efficiency standards. The controller supports trough/zero-voltage switching technology, which significantly reduces switching losses to maintain high efficiency over the entire load range.

Energy efficiency and features:

Optimised frequency control: The TEA2016AAT's switching frequency in all operating modes is designed to be outside the audio range, which, combined with the soft-start/soft-stop burst mode, effectively reduces audible noise.

Precise power management: The TEA2016AAT achieves precise and smooth switching between different operating modes (high power/low power/burst mode) to ensure disturbance-free power conversion.

In practice, power systems designed with the TEA2016AAT can achieve peak efficiencies of more than 94% while maintaining extremely low no-load power consumption, which is especially important for devices that require continuous power supply, such as networking equipment, security systems and medical instruments.

Application Areas and Design Flexibility

The TEA2016AAT's high degree of configurability and broad applicability make it ideal for a wide range of power supply designs.

Typical application areas include:

Consumer electronics: ultra-thin notebook adapters, LCD TVs, game console power supplies

Computer and office equipment: desktop power supplies, server power supplies, printer power supplies

Industrial and communication equipment: industrial control system, communication base station power supply, network equipment power supply

Professional lighting: LED driver power supply, stage lighting power supply
