The NCV8843MNR2G is a high-performance integrated DC to DC switching regulator part of the PMIC Voltage Regulator family. This device is designed to provide high output current accuracy, low dropout voltage, and low quiescent current- all without the need for additional external components. NCV8843MNR2G offers a robust and efficient power supply solution for many consumer, industrial, and automotive applications.

The NCV8843MNR2G is a voltage regulator that switches between high and low output voltage states to maintain a constant voltage level. It is designed to operate as a constant current source up to full VOUT ratings and is ideal for applications requiring high efficiency and low quiescent current. The device features an integrated adjustable high-side current sense and can be set to operate in either constant-voltage or constant-current mode depending on specific application requirements. Output over-current, over-voltage, under-voltage, and thermal shutdown protection features ensure stable and reliable operation.

The device’s versatile architecture allows it to be used as a linear regulator, a peak current-mode buck regulator, or a high efficiency buck regulator depending on the application need. Operating frequency is also adjustable and can range from 1KHz to 500KHz, allowing for much more flexibility in system design. In any buck regulator application, the NCV8843MNR2G can achieve a wide range of efficiency up to 95%, depending on how the device is operated.

One primary benefit of the NCV8843MNR2G is its integrated over-voltage and over-current protection polarity-reversal switches. These switches enable multiple input sources, such as multiple batteries and energy harvesters, to be connected in parallel to the output if needed. This feature is particularly useful for applications that could benefit from greater overall current capacity, or that could use multiple redundant sources in order to ensure higher levels of device availability.

In summary, the NCV8843MNR2G represents a versatile, efficient, and effective DC to DC switching regulator suitable for a wide range of applications. The device’s user-adjustable features allow it to be tailored to meet specific application needs, while its integrated protection features ensure reliable performance and system stability. Its range of operating frequencies, current capacities, and efficiency levels make it highly adaptable to a variety of application needs.
