I. TI GaN Power Stages: The High-Frequency, High-Efficiency Power Core

GaN power stages form the foundation of TI’s GaN product portfolio and serve as the core power units for various power conversion systems. Primarily comprising GaN FET devices with integrated gate drivers, they have completely revolutionised the design limitations of traditional discrete silicon MOSFET solutions, providing a highly reliable, low-loss foundation for all types of high-frequency power circuits.

1. Key Technical Advantages

Compared to traditional silicon-based power devices, TI’s GaN power stages offer significant performance advantages. Firstly, with ultra-high switching speeds and extremely low switching losses, GaN transistors switch at a rate far exceeding that of silicon MOSFETs. This substantially reduces switching losses under high-frequency operating conditions, supports operation at MHz-level frequencies, and effectively enhances power conversion efficiency. Secondly, with zero reverse recovery loss, they completely eliminate the voltage spikes, harmonic interference and additional losses caused by the reverse recovery of silicon devices, thereby reducing circuit EMI interference and simplifying filter circuit design. Thirdly, the highly integrated design combines a GaN power transistor and a dedicated gate driver on a single chip, eliminating the need for an external driver chip. This reduces the number of peripheral components, significantly minimises PCB footprint, and lowers the complexity of system-level routing as well as material costs. Fourthly, high reliability throughout the entire lifecycle: through rigorous process control and ageing tests, TI ensures the long-term stable operation of GaN power stages under high-temperature, high-frequency and high-load conditions, making them suitable for demanding industrial and automotive application environments.

2. Core Application Scenarios

TI’s GaN power stages are suitable for an extremely wide range of applications, covering various medium- and high-frequency power conversion equipment such as communication base station power supplies, server power systems, industrial motor drive units, laptop fast-charging adaptors, electric vehicle on-board chargers (OBCs) and photovoltaic micro-inverters; they serve as the core foundation for building high-performance power systems.

II. TI GaN Motor Drivers: High-Precision, High-Efficiency Drive Control Solutions

TI GaN motor drivers are integrated intelligent power modules (IPMs) customised for variable-frequency motor drive applications. They feature deep integration of GaN power devices, drive circuits, protection circuits and sensing units, focusing on resolving the pain points of traditional silicon-based motor drivers—such as low efficiency, high harmonics, high noise and bulky size—and represent a core solution for high-end motor control.

1. Key Technical Highlights

Firstly, exceptional inverter efficiency: leveraging the low-loss characteristics of GaN devices, TI’s GaN motor drivers achieve inverter efficiency of over 99 per cent. This significantly reduces wasted power consumption during motor operation, minimises equipment heat generation, eliminates the need for bulky heat sinks, and substantially optimises the thermal performance of the equipment. Secondly, high-precision, low-noise control. Featuring ultra-low dead-time and propagation delay, combined with precise slew rate control technology, these drivers effectively suppress motor current harmonics and reduce operating noise, enabling smooth motor speed regulation and high-precision torque control, thereby significantly enhancing equipment operational stability. Thirdly, the system boasts exceptional integration, incorporating comprehensive protection mechanisms against overcurrent, short circuits, overtemperature and overvoltage, whilst also featuring a high-precision current sensing unit. As no external protection or sensing components are required, the motor driver PCB area can be reduced by more than 50 per cent, greatly simplifying the overall system structure. Fourthly, it offers broad adaptability to operating conditions, supporting high-frequency speed control scenarios and perfectly meeting the demands of equipment with complex dynamic operating conditions, such as variable-frequency household appliances, intelligent robots, power tools, drones and electric vehicles.

2. Core Application Areas

Primarily used in high-end white goods with variable-frequency drives, industrial servo motors, smart robot joint drives, lithium-ion power tools, consumer drones, two-wheeled electric vehicles, and motor control systems for automated production lines, helping equipment achieve upgrades in energy efficiency, noise reduction, miniaturisation and high-precision operation.

III. TI GaN AC/DC Converter: A Compact, Low-Standby-Power Power Supply Solution

TI’s GaN AC/DC converters are off-the-shelf power conversion solutions designed for mains-to-DC power supply applications. Integrating high-performance GaN HEMT power devices and centred on a self-biased high-frequency QR flyback architecture, they offer ultra-high power density, ultra-low standby power consumption and a minimalist peripheral design, making them the preferred upgrade solution for small-to-medium power supply equipment.

1. Leading Products

TI has launched several mass-produced GaN AC/DC converter chips covering different power ratings: the UCG28824 is a 45W self-biased high-frequency QR flyback GaN converter, suitable for small-to-medium power fast charging and small household appliance power supplies; the UCG28836 is a 65W integrated GaN converter featuring ultra-low standby power consumption, capable of meeting the fast charging requirements of high-power portable devices. The entire product range requires no auxiliary winding power supply; utilising self-biased technology to simplify the circuit architecture, it significantly lowers the design threshold.

2. Key Product Advantages

Firstly, ultra-high power density: leveraging the high-frequency operating characteristics of GaN, the volume of passive components such as transformers and capacitors can be significantly reduced, enabling compact and lightweight power supply designs suitable for portable devices and compact equipment. Secondly, ultra-low standby power consumption: optimised power consumption performance under no-load and light-load conditions meets stringent global energy efficiency certification standards, significantly reducing the energy consumption of devices in standby mode. Thirdly, minimal design complexity and controllable costs: a single chip integrates the GaN power transistor, control circuit and self-bias circuit, requiring very few external components and eliminating the need for complex debugging, enabling rapid mass production and reducing R&D and production costs. Fourthly, it offers high stability and low EMI. By combining the zero reverse recovery characteristics of GaN with an optimised circuit topology, it reduces voltage and current spikes, minimises electromagnetic interference, and enhances the operational stability of the power supply system.

3. Core Application Scenarios

Widely used in small-to-medium power AC/DC conversion applications such as fast-charging adapters for mobile phones and laptops, smart home power supplies, power supply modules for small household appliances, industrial auxiliary power supplies, auxiliary power supplies for servers, and charging systems for small energy storage devices.
