AN79L04ME1 Application Field and Working Principle

AN79L04ME1 is an integrated circuit for voltage regulation. It is classified as a PMIC (Power Management Integrated Circuit) under voltage regulator and linear regulator. This type of IC is highly successful in power circuit design, primarily used in consumer grade mobile and digital devices. This article provides information on the application fields and working principle of AN79L04ME1.

Application Field of AN79L04ME1

AN79L04ME1 is commonly used in consumer grade mobile and digital devices. It is designed to be slightly higher voltage accuracy and can keep the voltage much more stable than other PMICs. It has the ability to provide constant voltage even when the current changes with a larger range of input voltage and load regulation than other PMICs. This ability makes it suitable for energy-sensitive applications where board space is a priority such as smart phone chargers, portable audio players and digital cameras. Additionally, it is suitable for powering FPGA, DSP, micro-controllers, and other digital ICs which require stable voltage.

Working Principle of AN79L04ME1

AN79L04ME1 is a voltage regulator that works by comparing the output voltage to a stable reference voltage. If the output voltage is too low, then the output will be increased until it reaches the reference voltage; if the output voltage is too high, then the output voltage will be decreased until it reaches the reference voltage. This process is done in an efficient and steady manner, which makes the output voltage maintain the same level regardless of the input voltage or load.AN79L04ME1 uses a Pulse Width Modulation (PWM) technique to regulate the output voltage by changing the amount of power supplied to the load. The PWM signal is generated based on the error between the reference voltage and the output voltage. This error signal is amplified and converted into a PWM signal, which is then used to adjust the duty-cycle of the power switch in an switching regulator application.

Conclusion

AN79L04ME1 is a highly successful and advanced PMIC for voltage regulator and linear regulator. It is capable of maintaining constant voltage even when the input voltage and load are changing. This feature makes it suitable for applications such as smart phone chargers, portable audio players and digital cameras. Additionally, it uses a PWM technique to regulate the output voltage, which makes it suitable for powering FPGA, DSP, micro-controllers, and other digital ICs which require stable voltage.
