EL7513IWT-T7A - An Overview

The EL7513IWT-T7A is a powerful, low cost and high performance LED driver designed for use in automotive, industrial, and consumer applications. This LED driver is part of the EL7513 LED Drivers family, which provide advanced features and functionality in a very small package, making it ideal for applications that need the highest performance and smallest footprint possible.

Application Field

The EL7513 offers a variety of features and capabilities making it ideal for a wide range of applications. It is designed for automotive, industrial, and consumer applications, such as headlights, marker lights, turn signals, lighting control applications, and more. The EL7513 also has a small form factor, which makes it ideal for applications where space is at a premium, such as mobile devices and wearable electronics. The EL7513 also offers high power efficiency, with a peak efficiency of up to 95%. This makes it ideal for applications that need to maximize power efficiency, such as battery operated systems, or applications that require robust operating temperature range. Additionally, the EL7513 supports dimmable LED drivers, allowing the user to control brightness.

Working Principle

The EL7513 employs a buck converter IC to provide step down conversion of input voltage. A buck converter is a type of DC-DC converter that reduces an input voltage by a chosen factor and provides output voltage which is lower than the input voltage. This is accomplished by using an inductor to store energy temporarily, as well as a switching transistor which switches between two states to provide the necessary control signals for the inductor. The output voltage of the EL7513 is controlled by varying the duty cycle of the transistor, using an internal or external feedback circuit. The duty cycle is determined by the ratio of the on-time (time when the transistor is switched on) to the off-time (time when the transistor is switched off). The output voltage is proportional to this ratio and can be adjusted to provide the desired output voltage. The EL7513 also has protection features which provide a fault and overloading protection to ensure safety of the LED and device. Additionally, the EL7513 features built-in thermal protection, which helps protect the device from excessive temperatures.

Conclusion

The EL7513IWT-T7A is a powerful, low cost, and high performance LED driver designed for use in automotive, industrial, and consumer applications. The EL7513 offers a variety of features and capabilities, including high efficiency, dimming, and built-in protection. The EL7513 is an ideal choice for applications that need the highest performance and smallest footprint possible.
