I. Isolated Power Modules (Integrated Transformer)

1. Product Positioning and Core Value

TI’s isolated DC/DC power modules (integrated transformer) are integrated power solutions designed specifically for applications requiring electrical isolation. They highly integrate core components such as power switching devices, control logic, rectifier circuits and isolation transformers within a single package, enabling electrical isolation between input and output without the need for external isolation transformers or complex peripheral circuits. The core value lies in resolving issues such as common-mode interference between high and low voltage, the risk of high-voltage breakdown, and signal crosstalk, whilst simultaneously delivering a compact form factor, high reliability and compliant isolation performance. This makes them ideally suited for applications with stringent requirements regarding isolation levels, safety and stability.

2. Key Technical Features

- Highly Integrated Monolithic Design: Incorporates an isolation transformer, power MOSFET, driver circuit and feedback control circuit, completely eliminating the need for external discrete transformers. This significantly reduces PCB footprint, minimises the number of BOM components, simplifies routing and manufacturing processes, effectively enhances system integration and stability, and reduces the risk of faults caused by the soldering and routing of discrete components.

- Compliant Isolation Protection: Supports high-level electrical isolation such as 3kVRMS and 5kVRMS, covering basic, reinforced and functional isolation specifications. It meets safety certification standards for industries including industrial, automotive and medical (e.g. relevant UL and IEC standards), effectively preventing high-voltage intrusion into the low-voltage side, protecting core chips and sensitive circuits, and enhancing the equipment’s immunity to interference.

- Wide Voltage Range and Stable Output: Covers a wide input voltage range, with common specifications including 3V–5.5V and 5.5V–20V. Output power is typically in the low-power range of 1W–2W, with stable and precise output voltage and excellent load transient response. This meets the isolated power supply requirements of low-power devices such as digital isolators, interface chips and sensors.

- Low EMI and high reliability: Utilises an EMI-optimised integrated transformer with extremely low parasitic capacitance between the primary and secondary windings. Compliance with electromagnetic compatibility standards such as CISPR 32 and CISPR 25 is achieved without the need for additional complex EMI filters; Wide operating temperature range: Supports operation from -40°C to 125°C, with multiple protection mechanisms including overcurrent, overvoltage, undervoltage and overtemperature protection, making it suitable for harsh industrial and automotive environments.

- Dual automotive and industrial grade configurations: A range of Q1 automotive-grade products has been launched, compliant with AEC-Q100 certification, suitable for automotive auxiliary power supplies, battery management systems and isolated power supply for in-vehicle communication interfaces; simultaneously covering industrial-grade specifications to meet isolated power supply requirements for industrial automation, PLCs, RS485/CAN bus systems, instrumentation and similar applications.

3. Representative Products and Application Scenarios

Typical products include the UCC33420-Q1, UCC35131-Q1 and UCC33020 series. The UCC33420-Q1 features a 4mm × 5mm ultra-compact leadless package, delivers 1.5W of output power and offers 5kV RMS reinforced isolation; The UCC35131-Q1 is an automotive-grade 2W isolation module with an input voltage range of 5.5V–20V, suitable for multi-channel isolated power supply in automotive applications.

Core application scenarios: isolated power supply for automotive communication interfaces, industrial bus (RS485/CAN) isolated power supply, low-voltage side isolated power supply for medical devices, sensor signal isolation, and cross-domain power supply for high- and low-voltage systems.

II. Power Modules (Integrated Inductor)

1. Product Positioning and Core Value

TI’s power modules (integrated inductor) offer a minimalist power solution for non-isolated, high-efficiency buck applications. They integrate core components—such as a synchronous buck controller, power switch, power inductor and compensation circuit—into a single package, featuring a compact footprint, high power density, high efficiency and ease of design. Engineers are spared the need for complex inductor selection, loop compensation and PCB optimisation; simply by adding a few input and output capacitors, a stable buck power supply can be rapidly assembled, making it the ideal choice for space-constrained applications and scenarios requiring rapid development.

2. Key Technical Features

- Extreme miniaturisation and high power density: Utilising innovative packaging technologies such as MagPack™ and 3D integration processes, the high-power inductor is built-in. Compared to traditional solutions using external inductors and power ICs, PCB footprint can be reduced by over 30%, whilst the compact package size (e.g., 2.8mm × 3mm) makes it perfectly suited for space-constrained products such as mobile phones, laptops, portable devices and compact industrial control boards.

- High Efficiency and Wide Load Range: Primarily utilising synchronous buck topologies, these solutions feature extremely low conduction losses and peak efficiencies exceeding 95%. They support light-load power-saving modes whilst maintaining high efficiency across the entire load range. Output currents span from 0.5A to tens of amperes, with support for single- and multi-output configurations. Certain products support stackable designs, allowing flexible expansion of output current to accommodate varying power load requirements.

- Minimalist design and rapid mass production: With maximum integration and minimal external circuitry, the design requires only a small number of passive components, eliminating the need for specialist power supply design expertise and significantly lowering the development threshold. Built-in comprehensive loop compensation and soft-start circuits prevent output overshoot and inrush current, reducing the need for debugging and effectively shortening product R&D and mass production cycles.

- Excellent EMI performance: Optimised internal layout and parasitic parameters allow placement close to the load, minimising interference from parasitic inductance. Combined with a dedicated packaging design, this easily meets industry EMI compliance requirements, reduces the need for external filtering components, and further reduces the solution’s footprint.

- Wide Temperature Range and Comprehensive Protection: Supports operation across a wide temperature range from -40°C to 125°C. Features multiple built-in protection mechanisms, including overcurrent, short-circuit, overtemperature and undervoltage lockout, ensuring stable power supply operation. Covers a wide range of specifications, including industrial, automotive and consumer grades, to meet the non-isolated buck power supply requirements of various electronic devices.
