PMIC – Voltage Regulators – DC DC Switching Regulators are essential components in any modern electrical system, particularly those that must interface with a variety of power sources or fluctuating power demands. For example, laptop computers, cell phones and other consumer electronics typically require some form of isolated, regulated DC power source in order to function correctly. Similarly, many industrial power applications require dedicated DC power systems to ensure reliable operation, such as motor drives in automotive, aerospace and other heavy industrial applications. The TB7110F(TE12L,Q) is a popular DC-DC switching regulator designed for such applications, and is capable of meeting the performance demands of a wide range of applications. In this article, we will discuss the various fields of application and working principle of the TB7110F(TE12L,Q) DC-DC switching regulator.

Fields of Application

The TB7110F(TE12L,Q) DC-DC switching regulator is an ideal choice for any application that requires an isolated, regulated power source. Due to its wide operating voltage range of 4.5 to 18V, it is well-suited for use in laptop, notebook and other consumer electronics. Additionally, it is well-suited for use in heavy industrial applications such as motor drives, where high current demands and tight voltage regulation are critical. The TB7110F(TE12L,Q) has the added benefit of a good EMI performance, making it suitable for use in applications with high levels of electromagnetic interference.

Working Principle

At the heart of the TB7110F(TE12L,Q) DC-DC switching regulator is a buck converter circuit. This circuit works by using an inductor and a diode to convert a DC input signal into an isolated, regulated DC supply. When the device is first turned on, current starts to flow through the inductor, which stores the energy in a magnetic field. When the switch is turned on, the energy stored in the magnetic flux is transferred to the output of the buck converter, driving current through the output capacitor and providing the regulated output voltage.

The current delivered to the output of the buck converter is also determined by a common control loop. This control loop senses the output voltage and controls the duty cycle of the powering switch, allowing the output voltage to be regulated within a set range. This process is continuous, and the output voltage remains regulated as long as the input voltage is constant.

In order to provide the best possible performance and reliability, the TB7110F(TE12L,Q) DC-DC switching regulator is equipped with a number of features. It has built-in EMI filters, as well as an over-voltage protection circuit and a thermal protection circuit. It also features a low quiescent current, allowing for higher efficiency in systems where a low idle-state power consumption is desired.

Overall, the TB7110F(TE12L,Q) DC-DC switching regulator is a well-designed, reliable component that is capable of providing a stable, regulated power source to a variety of applications. Its wide input voltage range, excellent EMI performance and advanced protection circuits make it an ideal choice for any application that requires a reliable, isolated DC supply.
