LX8117B-28CDT Application Field and Working Principle

LX8117B-28CDT is a device from the class of PMIC, or Power Management Integrate Circuit, specifically the voltage regulators subcategory and more specifically the Linear subcategory. It is an advanced voltage regulator that combines high accuracy, ultra-small size and low quiescent current in a single setup. It is one of the best regulators for smart phone, tablet and other portable applications, and provides a simple and convenient way for output voltage and current regulation.

This device combines both switching and linear regulators, using a combination of two chips and one inductor, and features a low noise output, an ultra-small size, high frequency operation and low power consumption making it one of the most advanced regulators in its category. The device also offers excellent line and load regulation, and uses an integrated 4A MOSFET and an integrated P-channel MOSFET for the switcher, allowing it to drive a load of up to 8A.

The primary application of the LX8117B-28CDT is in portable devices, where it can be used as a voltage regulator in applications such as mobile phones, tablets, and portable medical devices. It provides an output voltage of 4.1V to 28V, offering an adjustable output voltage that can be set through an external resistor divider. It also provides a low ripple and noise, and includes a precision of the 12µV maximum deviation from programmed output voltage.

The working principle of the LX8117B-28CDT is relatively simple and relatively straightforward. The device features a two chip setup, which includes an integrated 4A MOSFET for the switcher and P-Channel MOSFET for the linear regulator. The integrated 4A MOSFET acts as an active switch and the P-channel MOSFET acts as a linear regulator. The 4A MOSFET switch is used to step down the voltage from the input to a level that is accepted by the P-Channel MOSFET, while the P-Channel MOSFET is used to adjust the output voltage based on the external resistor divider.

The LX8117B-28CDT offers a wide variety of features, making it one of the most versatile voltage regulators available. It offers a low quiescent current, and a wide range of output voltage settings. It is also relatively small, which makes it ideal for use in portable devices. In addition, it features a high frequency operation, which allows for faster response times and makes it capable of driving higher loads. It also offers excellent line and load regulation, ensuring constant and reliable voltage output.

In conclusion, the LX8117B-28CDT is a versatile and advanced voltage regulator from the PMIC, or Power Management Integrated Circuit, category, specifically from the voltage regulators subcategory and more specifically from the linear subcategory. It features a two chip setup, which includes an integrated 4A MOSFET for the switcher and a P-channel MOSFET for the linear regulator. It offers a wide range of output voltage setting, a low quiescent current and a wide range of applications, making it perfect for use in portable devices such as mobile phones, tablets and medical devices.
