EL7566AIREZ

Introduction

The EL7566AIREZ is a synchronous, non-isolated, DC DC Switching Regulator (DC-DC SR). It is designed by Toshiba for industrial and consumer application requirements. The EL7566AIREZ can be used as a power supply in various applications such as automotive and communication systems. It is a highly efficient, regulated voltage source and can be easily implemented in a manufacturing environment.

Application Fields

The EL7566AIREZ is a DC-DC SR that is suitable for almost any application where a fixed and regulated voltage is required. It is most frequently used in automotive, industrial, and communication systems. It can function as a constant, high-efficiency power supply for LED light systems, motion control, motor controllers, and temperature controllers in automotive, industrial and communications systems.

In addition, the EL7566AIREZ can be used in AC-DC switching supplies. This device can provide regulated low voltage with high current and high power factor, making it ideal for AC-DC switching supplies with high efficiency, low component count and wide input voltage ranges. This device is also suitable for low-power DC-DC supplies and powerline communication.

Working Principle

The EL7566AIREZ is a DC-DC Switching Regulator that uses a synchronous flyback topology. This enables the device to provide a constant voltage over a wide range of input power levels. During normal operation, the primary switch is on at times, and the secondary switch is off. When the primary switch is on, it regulates the output voltage by controlling the on-time of the switch. When the primary switch is off, the secondary switch drives the output voltage down by transferring power from the primary side to the secondary side. The flyback topology also provides a low output ripple.

In order to provide a constant voltage, the EL7566AIREZ uses a voltage-mode-control (VMC) technique. This technique ensures that the output voltage is regulated by controlling the switching frequency. The output voltage is determined by the ratio of the primary winding inductance and the turned ratio of the transformer. The device also features a range of protections, such as over-voltage protection and over-temperature protection.

Conclusion

The EL7566AIREZ is a highly efficient DC-DC switch-mode power supply that is suitable for various applications. It is a synchronous flyback regulator that uses a VMC technique to regulate the output voltage. The device also has a wide range of protections, making it a reliable and safe power supply for industrial and consumer applications.
