RT7264EZQW Application Field and Working Principle

RT7264EZQW is a positive voltage regulator integrated circuit (IC) which belongs to the PMIC - Voltage Regulators - DC DC Switching Regulators family. Often abbreviated as VRs, these types of ICs ensure a regulated output voltage level and can carry out protection and adjustable features. The RT7264EZQW, in particular, offers industry-leading performance and reliability, helping to reduce design complexity.

Features

The RT7264EZQW offers several features that give it an edge over other VRs. It can provide a maximum output current of up to 3A and has an adjustable output range of between 0.8V and 5V. It also has a switching frequency of up to 2.0MHz and is capable of operating between -40°C and 125°C. The RT7264EZQW is also equipped with wide input voltage range of 4.75V to 22V and an extensive protection support that includes input voltage protection, foldback current protection, thermal shutdown and soft-start.

Applications

The RT7264EZQW can be used for a wide range of portable electronics applications, such as smartphones, tablets, digital cameras, and portable game consoles. It can also be used in automotive applications, as well as networking and computing applications. Its adjustable output range makes it a great choice for any application where precise voltage regulation is required.

Working Principle

The RT7264EZQW operates on the pulse width modulation (PWM) control principle. In this technique, the voltage output is regulated by rapidly switching the semiconductor between two output states. The switching is controlled by a high frequency oscillator, which is then modulated by a PWM signal generated by the IC. The PWM signal is further modulated by the voltage feedback signal which helps maintain a required output voltage even under varying load conditions.

The pulse width modulation technique ensures fast voltage regulation and high efficiency. The high switching frequency also helps reduce the size of the external filter components, minimizing the space and cost of the PCB design. The RT7264EZQW has been designed to provide an intuitive and easy to use solution for portable applications that require efficient and reliable voltage regulation.
