Working Principle
The NX20P5090UKAZ PMIC uses a buck topology for power conversion. The device is a digital integrated circuit that uses Pulse Width Modulation (PWM) to control the power delivery. It has a high frequency oscillator, which produces clock pulses at a fixed frequency with the duty cycle determined by the control logic. The duty cycle of the oscillator determines the amount of power delivered to the load. The higher the duty cycle of the oscillator, the higher the power delivered to the load. The power switch is a MOSFET, which is triggered when the control logic sends a signal. The power switch turns on and off based on the signal, and the duty cycle of the oscillator determines when it turns on and off. The voltage at the input of the PMIC is regulated by an external power supply, and the voltage at the output is regulated by an internal voltage regulator. The voltage regulator ensures that the voltage at the output remains constant, even when the voltage at the input changes or fluctuates.
Conclusion
The NX20P5090UKAZ PMIC is a versatile power management IC, designed for automotive applications and suitable for a wide range of voltage inputs. It has wide operating voltage range, multiple protection functions, high efficiency and peak current, and integrated power switch, load drivers, and high-current PMOSFET driver. The device uses a buck topology for power conversion, and PWM control for regulating power delivery, ensuring constant voltage delivery at the output even when the input voltage fluctuates.
