?PMIC - Power Distribution Switches, Load Drivers
The NX20P3483UKZ is a multiphase Pulse Width Modulated (PWM) voltage regulator specifically designed for low-to-medium current and high-performance applications that require voltage regulation, load sharing, and monitoring functions. This type of controller works in “multi-phase” manner. It consists of a multiple blocks of voltage control circuits, each with independent regulation for a given phase, and the power is distributed to the loads through switches. The PWM signal is employed to turn on and off the power distribution switches in order to supply the load. In this manner, the current is regulated in response to the output voltage feedback.
Application Fields
NX20P3483UKZ is suitable for applications requiring high-performance and high-density. It is especially useful for powering systems with multiple battery cells, as it can provide a precisely regulated voltage and current across multiple stages, as well as current sensing, temperature sensing and control. It is also suitable for applications where strict voltage regulation and dynamic performance are required, such as in digital signal processors, audio amplifiers, LED backlighting and motor drives.Working Principle
The basic functioning concept relies on the cyclic driving of the power switches. An independent loop with an internal PWM control block regulates each phase independently, providing an accurate and reliable voltage and current regulation. The voltage regulation is achieved by modulating the duty cycle of the imported PWM signals to the power switches. The PWM control approach is used to regulate the amount of current supplied to the load based on the given output voltage and load current feedback. The power switches are enabled according to the duty cycle ratio, and when all of the switches are turned on, the current is delivered to the load. The parameter of interest is the output voltage, and hence the voltage control is normally implemented in the form of a voltage regulation loop.The NX20P3483UKZ implements a current sensing technique, enabling independent information to be obtained from each phase. This provides a more accurate current monitoring, and hence more precise current regulation. In addition, temperature is monitored and the duty cycle of the power switches is adjusted accordingly. This feature helps increase the stability and performance, as well as the reliability of the device.Input/Output Considerations
NX20P3483UKZ is designed for a wide range of applications, so certain input/output considerations must be taken into account in order to ensure the desired performance. The input voltage should range from 7-10V, and it should provide adequate current to the device. The output current can range from 0-20A for one phase, with a maximum of four phases supported. The input and output capacitors should be chosen according to the applicable application. The output voltage accuracy should be between 0.5% and 2%, and it may vary slightly depending on the load conditions and the accuracy of the input voltage.Conclusion
Overall, the NX20P3483UKZ is the perfect choice for applications requiring high-performance and high-density voltage and current regulation, load sharing and sensing capabilities. Its wide range of features allows it to be used in a variety of applications, and it can provide a reliable and accurate performance in these applications.The specific data is subject to PDF, and the above content is for reference
