Datong University Shiping launches IoT power solution based on TI products

Datongda Holdings, a leading semiconductor component distributor dedicated to the Asia-Pacific market, announced that its company will launch its IoT power solutions based on TI products, including high-integration controllers and capable boards. The UCC28880 and UCC28910FET solutions are optimized for size, to high-performance flyback controllers such as the UCC28704, UCC28740, and UCC28722 that combine size, performance, and cost.

As the Internet of Things enters traditional home life with functions such as communication, it needs to upgrade and meet the additional power added by IoT devices. Since the power requirements of these devices are different from those of conventional devices, designers need to change the power supply to a flyback converter to maintain a certain level of performance. At the same time, it still needs to switch from 120VAC and 240VAC household input voltage to 208VAC and 480VAC commercial input voltage. To ensure the best user experience, designers must spend some time choosing and designing the right power source.

High-order control functions such as these valley switching and high-order AM/FM modulation modes introduced by TI's agent, can not only maximize the loss and size, but also maximize the performance. Speed ​​up the design process. These include:

Descriptive product specification sheet with features and application notes;

Provide application notes for more details on design and use;

Exce l and / or MathCAD design calculation systems for parameter and component selection;

The hardware that the SPICE model can use to verify functionality before hardware construction is completed;

A reference design showing dimensions and performance under other operating conditions.

The new and exciting new features brought about by the Internet of Things are not without cost, because it requires a completely new power supply design. To solve this problem, TI offers high-performance devices that meet all needs and a rich set of design support tools to help engineers quickly optimize and power their power supplies.

The 1W auxiliary power supply (100V-450VDC, 5W, 80% efficiency) reference design for AC/DC power supplies is a compact 5W wide high voltage DC input auxiliary power supply with multiple output voltages.

Product Features

The TIDA-00708 is a 5W multi-output auxiliary power supply designed for applications in industrial, server, telecom and consumer electronics systems. The reference design is a flyback converter implemented using the UCC28881 device, which integrates the controller, 700V power MOSFET, and internal current sensing into a single device. The design is simple, compact, and low cost because of the small number of components and all necessary protections such as output overcurrent, output short circuit and over temperature conditions. The hardware is designed and tested to meet EFT requirements and meets the Department of Energy (DoE) Class VI low power efficiency performance.

The 12V voltage reference design using the UCC28910's 0.35A isolated primary-side feedback loopback is a compact and cost-effective universal AC input voltage that can be turned to 12V through the UCC28910 at 4.2W.

Product Features

The PMP30044 reference design uses the UCC28910 quasi-resonant flyback converter to generate an isolated output (12V@ 0.35A). The UCC28910 integrates a 700V power FET and provides primary side regulation, eliminating the need for optocouplers and reducing the total number of components. It is a cost-effective design.

The 108VAC-305VAC input voltage, 3.6V/5mA flyback reference design is a very small high-voltage and low-voltage line AC input that passes through the UCC28910 and becomes 3.6V at 18mW.

Product Features

This low-power flyback power supply is designed to minimize total input current while providing a low power output of 3.6V/5mA. The output is functionally isolated from the input. The physical size is minimized by using the UCC28910 controller with integrated high voltage MOSFET and primary side regulation.
