Applications

The LM26484SQE/NOPB is designed to be applied in a host of mobile, media, and consumer applications. It can be used to power mobile handsets, tablets and other low-voltage applications in the consumer electronics, automotive, industrial, and medical fields. It offers superior thermal performance, efficient use of board space, and long operation lifespan. These features make it an ideal choice for any system requiring a long-lasting, reliable and powerful power source that can support a wide range of voltages and loads.

Working Principle

The LM26484SQE/NOPB is a quad DC/DC regulator that employs a switching regulator design to provide adjustable and fixed output voltages as well as providing high efficiency and very low noise operation. It features four independent step-down regulators with a single input voltage between 2.6V to 5.5V which can provide up to 800mA of continuous current for each channel for a total of 3A maximum power output.The switching regulator works on the principle of conversion of an alternating current into a direct current, with the help of an inductor, capacitor and transistor, along with MOSFET circuitry connected in parallel with the inductor as well as providing high switching speeds. When the switch is closed, the output voltage is regulated, and the maximum current isn’t exceeded. When the switch is opened, the stored energy in the inductor is discharged, which transforms into the desired output voltage.

Conclusion

The LM26484SQE/NOPB is a highly efficient multi-channel, dc-dc and linear regulator integrating four independent step-down regulators and a comprehensive set of integrated protections. It can provide up to 800mA of continuous current per channel and a total of 3A output power. Its features combined with an elegant and compact package make this IC an ideal solution for multiple low-voltage applications. Its switching regulator design ensures efficient and low-noise operation, making it an excellent choice for powering any system needing a reliable and powerful power source.
