It also has a small size, making it suitable for mobile applications.

EL7642ILTZ Working Principle

The output voltage is regulated by using a combination of a linear regulator using an integrated error amplifier and a synchronous buck regulator. The voltage detector senses the output voltage, amplifies, and compares the amplified voltage with the voltage reference. This comparison is fed back to the linear regulator to regualte the output voltage. The synchronus buck regulator actively regulates the output voltage within an acceptable voltage range. The linear regulator then regulates the voltage within a very small range known as the regulation window. This regulation window is determined by the difference between the reference voltage and the upper and lower thresholds of the error amplifier.

Conclusion

The EL7642ILTZ is an innovative voltage regulator specifically designed for special purpose applications. With its wide input voltage range and small size, it is suitable for various markets and industries such as industrial, medical, and automotive. It has many features such as high efficiency, small footprint, and RoHS compliance. Most importantly, the EL7642ILTZ works on the basis of a combination of a linear regulator and a synchronous buck regulator to regulate the output voltage within a very small range.
