XR76112ELTR-F is a kind of dc-dc switching regulator, which is designed to provide higher efficiency and power density performance at a lower operating temperature. As a DC-DC switching regulator, it can be used to convert voltage from an external AC or DC supply to meet the requirements of a wide range of applications. This article will discuss the application field and working principle of XR76112ELTR-F.

Application Field

The XR76112ELTR-F is a flexible device with many application fields. It can be used in a number of different systems and components including telecom infrastructure, industrial, consumer electronics, and many other applications that require a reliable, high efficiency AC/DC power supply. For example, it can be used in an outdoor enclosure to reduce environmental requirements and improve product longevity. It can also be used in consumer electronics such as mobile phones, tablets, and other small portable devices for efficient power management. Finally, it can be used in automotive applications as a solution for power conversion efficiency and power loss reduction.

Working Principle

XR76112ELTR-F operation is based on a single switch-mode power supply, which converts an external DC or AC source into a regulated DC output. It is designed to provide higher efficiency and power density performance than linear regulators at a lower operating temperature. The device new architecture combines the advantages of both synchronous and non-synchronous buck, allowing the power train to use the most cost-effective solution.

The XR76112ELTR-F has a constant on-time (COT) control and operate as a peak current-mode DC-DC converter, consisting of a power MOSFET, an inductor, and an output capacitor. This feature enables the device to detect and respond quickly to changes in load, resulting in improved efficiency and power density. The on-time of the switching transistor is determined by an external reference voltage and an internal current-sense threshold. This permits the device to regulate the output voltage even under heavy load.

The XR76112ELTR-F utilizes a low-side MOSFET for power conversion. The power MOSFET is operated in either its analog or digital mode to control the output voltage. In the analog mode, the device is configured to maintain a constant output voltage. In the digital mode, the voltage regulation is controlled by an external reference voltage. The device also features a pre-biased mode that allows for faster response and a low-noise operation in prebiased applications.

Overall, the XR76112ELTR-F is a great choice as a DC-DC switching regulator as it provides higher efficiency, power density performance, and reliability over a wide range of applications. Its COT control, analog and digital modes, and low-noise operation make it an excellent choice for any application where power efficiency and reliability are important.
