PMIC - Voltage Reference governs a system’s electrical performance and efficiency. The LM4128CQ1MFX4.1/NOPB is a voltage reference designed specifically for Network Interface Card (NIC) applications. It provides an adjustable output voltage of either 1.8V or 2.5V, depending on the configuration. The device can generate a wide range of output currents from 0.1A to 2.5A, making it ideal for network physical layer applications. This article will discuss the application fields and working principles of the LM4128CQ1MFX4.1/NOPB.

The LM4128CQ1MFX4.1/NOPB is ideal for networking applications such as Ethernet and serial communication channels. It is also suitable for power supply voltage regulation and monitoring, analog-to-digital conversion, and other power-related operations. The device has a precise output voltage accuracy of ±2% and a low dropout voltage of typically 0.7V, making it suitable for low voltage applications.

The LM4128CQ1MFX4.1/NOPB is a cost-effective voltage reference that utilizes a low-noise, low-output voltage reference design, consisting of a pair of high-precision resistors, a precise comparator, and a precise bandgap reference circuit. In the event of line voltage fluctuations or momentary power loss, the voltage reference automatically compensates for the change in line voltage, providing a constant voltage to the system.

The LM4128CQ1MFX4.1/NOPB also features an over-temperature protection circuit. This circuit monitors the temperature of the device and shuts down the reference supply when the temperature exceeds a predefined threshold. This helps protect the device from overheating and prevent damage due to excessive heat.

The LM4128CQ1MFX4.1/NOPB also features an adjustable current-limit circuit. The current-limit is adjustable via an external sense resistor, allowing users to set a maximum output current for the device. This helps to prevent over-current conditions and enables the device to meet different power requirements.

In addition, the LM4128CQ1MFX4.1/NOPB also features an adjustable power-good comparator threshold. This allows users to set a predefined voltage level, at which the power-good signal will be generated. This signal can be used to indicate that power is from a reliable source.

The LM4128CQ1MFX4.1/NOPB is an ideal choice for networking applications that require precise output voltage control and high current output. Its precise output voltage accuracy, low dropout voltage, over-temperature protection, adjustable current-limit, and adjustable power-good comparator threshold makes it an ideal choice for a variety of power-related applications.
