EL7581IREZ-T13 Application Field And Working Principle

PMICs (Power Management Integrated Circuits) are rapidly becoming an increasingly popular component of many modern systems and are often used to provide system power supply regulation, power sequencing, and monitoring functions. The EL7581IREZ-T13 is a special purpose voltage regulator that is designed to provide high current output with efficient and stable regulation. In this article, we will discuss its application field, as well as its working principle.

Application Field of EL7581IREZ-T13

The EL7581IREZ-T13 is designed for use in a variety of applications, including datacom, consumer audio/video, wireless, automotive, and consumer electronics. It is especially well-suited for portable systems that require a high-current output with an efficient, stable voltage regulation. The EL7581IREZ-T13 is also capable of providing up to 2A of continuous output current while operating in a very small package. The device also features both low-noise and wide input voltage range with ultra-fast transient response. This makes the EL7581IREZ-T13 ideal for applications requiring good system power reliability.

Working Principle of EL7581IREZ-T13

The EL7581IREZ-T13 utilizes PWM (Pulse-width Modulation) technology to regulate its output voltage. This is accomplished by using an adjustable reference voltage and adjusting the ON time of the PWM output, which is then directly proportional to the output voltage. The device also features internal voltage feedback, which is used to detect the output voltage level and ensure that the output voltage is properly regulated.In addition to regulating the output voltage, the EL7581IREZ-T13 also features multiple protection features, including over-voltage, over-temperature, and over-current protection. This makes the device well-suited for use in a wide range of applications.

Conclusion

The EL7581IREZ-T13 is an excellent example of contemporary voltage regulators that can provide high performance and reliable functionality in a small package. It offers wide input voltage range, low-noise, and fast transient response, making it ideal for multiple application fields such as datacom, consumer audio/video, wireless, automotive, and consumer electronics. In addition to regulating the output voltage, the device also features multiple protection features, including over-voltage, over-temperature, and over-current protection.
