EL7584IRZ

PMIC - Voltage Regulators - Special Purpose

The EL7584IRZ is a special purpose voltage regulator designed for various types of applications. It is capable of driving LEDs, providing regulated voltage for components, and providing a regulated output voltage for various loads. It is designed for a wide input voltage range of up to 48V, allowing for a maximum output current of 15A. The EL7584IRZ is an excellent choice for applications that require a robust and reliable voltage regulation.

EL7584IRZ Application Field

The EL7584IRZ is well-suited for applications that involve driving high power LEDs, providing a regulated operating voltage for components and loads, and providing a regulated output voltage for other loads. It is ideal for applications like automotive, industrial, medical, and consumer electronics that require a stable regulated power supply.

The EL7584IRZ can be used to drive high power LEDs due to its ability to maintain constant voltage over a wide range of load conditions. This allows for a uniform light output from the LEDs. It is designed to work with power LEDs up to 12W and provides a regulated voltage for higher wattage LEDs such as P-type and S-type. The EL7584IRZ is also suitable for applications that require a precise regulated voltage for components and in other loads.

EL7584IRZ Working Principle

The EL7584IRZ is designed with a voltage feedback loop to regulate its output voltage. This feature enables the EL7584IRZ to maintain a precise output voltage for loads. The voltage output of the device is based off a “proportional” comparison between the input voltage and the feedback voltage. The EL7584IRZ will regulate the output voltage according to the input voltage, so that the output voltage remains at the preset value.

In addition to the voltage feedback loop, the device also has over current protection. The EL7584IRZ includes a constant current limit circuit that shuts down the output when the current exceeds a preset limit. This protection feature helps to protect the device from overloads and provides a safety feature for the application.

The EL7584IRZ also has thermal protection, which shuts down the output when the temperature of the power switch exceeds the preset limit. This ensures that the device does not overheat and can protect against short circuits.

Conclusion

The EL7584IRZ is an excellent choice for applications that require regulated voltage, reliable current delivery, and thermal protection. It has a wide input voltage range and can drive LEDs up to 12W in power. Its voltage feedback loop ensures a precise regulated output voltage for a variety of load conditions. The over current protection and thermal protection make the EL7584IRZ a safe and reliable choice for a wide range of applications.
