The NX9548ILQ-TR is a DC-DC buck switching regulator from Nexperia, designed to regulate the voltage from an input source to a desired output. It is part of the PMIC - Voltage Regulsators-DC DC Switching Regulators category. It typically used to regulate the voltage level of a system or a component within a set range. It optimizes system performance, power efficiency, and power quality, as well as being able to reduce costs.

The NX9548ILQ-TR offers a field-effect output voltage stability with a wide range of operating frequencies. It is capable of outputting a maximum of 3.2A, with a power output of 4.9 W. It is a low-noise, high-frequency switching regulator. It is suitable for automotive, industrial, and consumer applications. This device is available in a thermally enhanced HTSSOP-12 package, with an operating temperature range from -40 to +85 °C.

The working principle of the NX9548ILQ-TR is quite simple. The input voltage from a DC source is converted to a regulated output voltage by a series of switching transistors and operating at high frequency. This high-frequency operation reduces the size of the inductor and switch to miniaturized sizes and allows for more efficient conversion. During the process, transistors quickly switch on and off at the oscillator frequency. When the transistor is “on,” the inductor is energized, storing energy and creating a magnetic field. When it is “off”, the field collapses and the capacitor stores the energy and provides the output voltage.

The NX9548ILQ-TR uses Nexperia’s proprietary SmartPSR™ techology, which enables a high level of system integration. This open loop architecture provides protection against output voltage instability as well as improving system performance and robustness. The SmartPSR™ also increases the efficiency of the switching regulator, ensuring less heat dissipiation and quieter operation. Furthermore, the device utilizes integrated load extrapolation and voltage feedback technology, allowing for input voltage variations to be compensated and the output preset fixed.

Overall, the NX9548ILQ-TR is an excellent solution for any application that requires a voltage regulator for power supply needs. It offers high efficiency, low noise, and a high output current of up to 3.2A. The integrated SmartPSR™ technology ensures a stable output voltage, regardless of fluctuating input signals, allowing for efficient and reliable power management. As such, the NX9548ILQ-TR is an excellent choice for automotive, industrial, and consumer applications.
