The TS80003-QFNR is a device in the specialised power management range of integrated circuits manufactured by its developer, China\'s Topins Technology. It is specially designed to enable cost savings while providing high efficiency, reliable power conversion in 9 different combinations. The TS80003-QFNR is a highly efficient, compact 4-channel buck regulator which can generate 5V/3.3V, 5V/1.8V, 5V/1.2V or 5V/0.8V output combinations. At a maximum efficiency of 94.2%, it enables up to 10A of total output current and is able to dynamically adjust the load current, voltage and frequency as needed in order to maximise efficiency and reliability. The TS80003-QFNR is a flexible solution for many application fields and also features several key features such as excellent thermal performance, low EMI, embedded safety functions, and a high temperature operating range.

Application fields

The TS80003-QFNR is well equipped to handle a wide range of applications. Some examples include mobile phones, laptop computers, tablets, automotive displays, set top boxes, and any other system requiring up to 10A of output current at different configurations. Additionally, since it offers excellent thermal performance, it is well suited to applications which require cooling solutions, as it can be placed directly on the PCB without taking up a lot of space or reducing the power efficiency.

Working Principle

The TS80003-QFNR operates via buck conversion and is able to produce multiple voltage combinations, depending on the user\'s requirements. This is done by using two pins connected to an internal voltage selector, allowing the user to define a voltage combination which is perfect for their needs. It is important to note, however, that when one of the pins is set to 0V, the corresponding output is disabled. Additionally, when both of the pins are set to 1.5V, the device acts as a single output converter.

The internal architecture of the device includes protection circuits which detect over current, short circuit and thermal overload. It is also capable of monitoring the temperature of the device which enables it to enter a safe mode and avoid any potential damage. The device can be set up in either continuous or pulse skip mode, as required by the user.

In terms of operational safety and reliability, the TS80003-QFNR also has internal cure feedback, over voltage protection, under voltage protection and dynamic current limit. Finally, the device also has an adjustable switching frequency which enables it to switch at a frequency up to 2.2Mhz, allowing the user to choose the optimal frequency for their application.

Conclusion

The TS80003-QFNR is an excellent power management integrated circuit developed by Topins Technology. It is highly efficient, compact, and is able to generate up to 10A of output current from different voltage configurations. Furthermore, its excellent thermal performance, high temperature operating range, low EMI, and embedded safety functions makes it an ideal solution for many applications. As such, it is an ideal choice for those who seek a reliable and cost-effective power management solution for their projects.
