EL5525IREZ Application Field and Working Principle

The EL5525IREZ is a special-purpose voltage regulator used mainly by automotive manufacturers to efficiently manage their power systems. It is a Pulse-Width Modulated (PWM) voltage regulator with integrated transistor drivers, available in a wide range of output current ratings that meets the needs of various systems\' requirements. This product has been designed and tested to meet the highest standards of quality and reliability.

The EL5525IREZ is designed to regulate the output voltage in a vehicle\'s electrical system regardless of changes in the input voltage, making it an ideal choice for automotive applications. It is compatible with supply voltages from 8 V to 16 V, providing a regulated output voltage of 5 volts. It has a wide input voltage range and a high load current capability, enabling it to drive up to 5 A of load current. It also has advanced safety features such as under-voltage lockout (UVLO), over-current protection (OCP) and thermal shutdown (TSD).

Applications

The EL5525IREZ is suitable for a wide range of automotive applications where efficient and reliable power regulation is essential. It has been extensively tested and is suitable for use in a wide variety of vehicles, including luxury cars, commercial buses and trucks, as well as ATVs and other off-road vehicles.

The EL5525IREZ is ideal for applications such as powertrain control units and engine control units, windshield wiper systems, remote door locks and lights, power steering and engine management systems, and infotainment systems.

Working Principle

The EL5525IREZ is a pulse width-modulated (PWM) voltage regulator. In a PWM voltage regulator, the output voltage is regulated by switching the transistor on and off very rapidly. The output voltage is then regulated by adjusting the duty cycle of the switching frequency. The EL5525IREZ is designed to maintain an accurate output voltage despite variations in the input voltage. This is achieved by comparing the output voltage to a reference voltage, and then adjusting the duty cycle accordingly.

The EL5525IREZ voltage regulator also includes additional safety features, such as under-voltage lockout (UVLO), over-current protection (OCP) and thermal shutdown (TSD). These features protect the device against damage due to excessive current or temperature, as well as to prevent it from outputting a voltage below the required level.

Conclusion

The EL5525IREZ is a reliable, efficient and cost-effective voltage regulator for automotive applications. It is designed to maintain an accurate output voltage over a wide input voltage range, and has advanced safety features for increased reliability and safety. This product is ideal for a number of automotive applications, including powertrain control units, engine control units, windshield wiper systems and engine management systems. The EL5525IREZ is the perfect choice for automotive manufacturers who demand the highest quality and reliability in their power systems.
