EL7566DRE-T13 Application Field and Working Principle

The EL7566DRE-T13 is an integrated an integrated high efficiency, high current buck/boost converter that operates from a 3.3V to 5.5V supply and can deliver up to 6A of continuous output current. It includes an integrated regulator of the highest performance, allowing it to be used in the most demanding applications. This versatile DC-DC switching regulator is capable of producing a wide range of adjustable output voltage types to optimize power management needs. It also offers excellent efficiency and transient response, with low output noise and ripple, making it ideal for powering precision system components.

Application Field

The EL7566DRE-T13 is optimized for point-of-load (POL) applications where the highest efficiency and current is required. This can include pico-ampere to kilo-ampere load current applications such as telecom, industrial, automotive, computer, and point-of-load systems. It can also be used to power portable handheld products such as test and measurement applications, mobile products and portable medical instruments.

Working Principle

The EL7566DRE-T13 DC-DC converter is a CMOS buck/boost converter topology with a high efficiency regulator. It includes hysteretic control to provide the most efficient power conversion for its selected application. The power transistors are an n-channel, low-side switch and a p-channel, high-side switch. The operating current of the device is limited by a user adjustable current control setting located externally on the board. The internal voltage regulator is designed to make sure that the desired output voltage of the device is achieved and maintained even under varying loads.

The EL7566DRE-T13 features an integrated over-voltage detection circuit for input and output, reverse current protection, over-temperature protection and abnormal mode detections. It also includes two-stage over-current protection with a power-on reset to prevent system damage by resetting after an incident of severe over-voltage or over-current. The device is also protected against externally-applied voltage on the control pins.

Conclusion

The EL7566DRE-T13 DC-DC switching regulator is the perfect solution for a variety of point-of-load applications. With its integrated regulator, it allows for excellent efficiency and can deliver up to 6A of continuous output current. Its hysteretic control and integrated protection circuits ensure reliable, safe operation of the device even under varying loads. In addition, its robust design allows it to withstand externally-applied voltage on control pins and it features a power-on reset for additional safety.
