Introduction
TFS758HG is a family of AC-DC converters, offline switchers and power management integrated circuits (PMICs) designed for a wide range of applications such as general purpose isolated and non-isolated switching power supplies, isolated power converters, DC batteries, motor controllers, battery chargers, audio pre-amplifiers, radios and others. It is capable of handling input voltages ranging from 5V to 400V, output currents up to 10A, and provides all the features required to build efficient and reliable switching power supplies and power converters.

Application Fields
The TFS758HG has two main application fields; offline, or non-isolated conversion, and isolated conversion. In offline applications, TFS758HG can be used for a variety of power conversion, such as converting a fixed voltage input of 12VDC/24VDC to multiple outputs for powering LED displays, motors, or other peripheral devices. Additionally, TFS758HG can be used as an active balancer or buck converter for applications that require a voltage and current to be actively regulated.

For isolated applications, TFS758HG provides a cost effective switched mode power supply solution. It features galvanic isolation between the input and output up to 1000VAC, allowing designers to implement isolated power supplies with fewer components. It can also be used for line feed applications, such as providing isolated power and input/output voltage matching in telecom systems, automotive, and industrial applications.

Working Principle
TFS758HG works via a unique switching technique called Burst Mode Control (BMU). BMU uses an inductor to store energy during the on-time of the switching cycles, and a capacitor to store energy during the off-time of the switching cycles. As the inductor\'s energy is increased during the on-time and decreased during the off-time, this helps maintain regulation of the output voltage. The BMU technique also significantly reduces power dissipation during the switching cycles, allowing the TFS758HG to maintain its high efficiency levels.

The BMU technique used by TFS758HG integrates various circuit protections, such as over-voltage, under-voltage, overload, and over temperature. These protections help during system start-up, as well as during normal operation, ensuring the system stays safely in its stable state. Additionally, the TFS758HG includes integrated gate drivers, allowing designers to reduce circuit board size and response time. The TFS758HG can also be synchronized to an external clock, allowing designers to synchronize multiple switched mode power supplies.

Conclusion
The TFS758HG is a family of AC-DC converters and power management integrated circuits (PMICs) designed for a wide range of applications such as offline and isolated conversion. Its main feature is its Burst Mode Control (BMU) switching technique, which allows it to handle a wide range of input and output voltages and currents and maintain an efficient and reliable switching power supply. It provides various circuit protection features, integrated gate drivers, and can be synchronized to an external clock, making it a flexible and cost effective solution for various types of power conversion.
