IRU1260CM Application Field and Working Principle

PMIC or Power Management IC is one of the essential components of various equipment and systems, such as automotive electronics, communications, industrial control and military applications. IRU1260CM is a three-terminal regulator belonging to the special purpose category, designed for automotive applications, offering excellent performance and exceptional value.

Application Field

IRU1260CM is an ideal choice for automotive-style regulators which feature short drop-out, low power dissipation and high performance. Its applications include systems requiring a dual voltage-level device, to solve the problem of low dropout, as well as those in need of protection against over-current or over-voltage. The device provides excellent performance and is highly reliable when used in situations where multiple-polarity systems require a reliable high-current supply. It also offers a variety of protections, enabling full control of the process.

Features

The IRU1260CM offers a variety of features such as high-frequency, short-on-time, circuit protection and improved performance at low junction temperatures. The device also features voltage mode and current mode protection, enabling reliable control of any type of load. Its low drop-out characteristics also provides it with an excellent power management solution, offering excellent efficiency. The device also offers an adjustable current limit, making it suitable for automotive applications as well as for any other environment where an adjustable current limit is required.

Working Principle

IRU1260CM operates on a linear regulator principle, relying on a voltage reference, an error amplifier, a current limit amplifier and a series pass transistor. The voltage reference is used to provide a setting voltage in the feedback loop, while the error amplifier amplifies the difference between the load voltage and the reference voltage. This amplified voltage is then used to control the current limit amplifier and series pass transistor, which in turn, delivers the current to the load.If the load is stable, the set voltage remains regulated and is maintained until the voltage reaches the set voltage, at which point it will begin to decrease as the series pass transistor adjusts the current limit. If the load is changing, the regulation voltage adjusts itself automatically, allowing for the critical current regulation needed for efficient power management.

Conclusion

The IRU1260CM regulator offers an ideal solution for providing reliable and accurate voltage regulation, making it an ideal choice for automotive applications. Its low drop-out characteristics also make it suitable for systems requiring protection against over-current or over-voltage. With its robust design, exceptional value and performance, the IRU1260CM is a reliable and cost-effective power management solution.
