The NCP51460SN33GEVB is one of the most popular evaluation and demonstration boards and kits. It is designed with the most advanced and up-to-date technology, which allows it to be used in various applications. In this article, we will discuss the application field and working principle of the NCP51460SN33GEVB.

The NCP51460SN33GEVB is a high-power, low-voltage and low-noise LED driver controller featuring the NCP1460 device, which supports dimming from 0.5 V to 10 V. The secondary-side linear regulator enables constant current regulation at high efficiency, regardless of the deviations in power supply or load conditions. The NCP51460SN33GEVB offers the user the ability to drive 30 LEDs with low enough noise that they can be operated in close proximity to audio applications. It is also well suited to other applications such as signage, general illumination, and automotive lighting.

The main feature of the NCP51460SN33GEVB is its ability to accept multiple input voltage levels, which is ideal for applications using out of spec power supplies or where variable LED string applications are needed. The LED driver only requires a single input voltage, but it can accept multiple hot-swapped input voltage levels. By supporting a range of input voltage levels, the driver maintains the LED power on each driver channel, while also adjusting the output current waveform depending on the input voltage.

The NCP51460SN33GEVB also features a secondary linear regulator to set the LED current level constant, regardless of load or power supply deviations. The LED driver is capable of maintaining a stable LED current level over the entire input voltage range, which is ideal for applications where the LED strings can suffer from power supply variations.

The NCP51460SN33GEVB can be used in different applications. It is suitable for lighting systems, panel displays, and medical diagnostic units. It can also be used in automotive lighting systems, LED lighting applications, and in any application requiring constant intensity LEDs. The NCP51460SN33GEVB offers a great solution for applications where the LED strings can suffer from power supply variations. It is also applicable for other applications such as signage, general illumination, and automotive lighting.

In terms of its working principle, the NCP51460SN33GEVB works on a simple but effective model. The primary side of the driver utilizes an NCP1460 controller connected to an external voltage regulator, which regulates the output current level, regardless of the input voltage level or load on the LED strings. The secondary side of the driver then utilizes a low-power linear regulator to set the LED current level constant, regardless of input voltage or load. The result is a safe, efficient, and reliable LED driving solution.

In conclusion, the NCP51460SN33GEVB is an advanced and highly efficient LED driver controller that allows for the use of multiple input voltage levels and low-noise operation in close proximity to audio applications. Its versatile design makes it suitable for a wide range of applications, from lighting systems, panel displays, and medical diagnostic units, to automotive lighting and general illumination. Finally, the NCP51460SN33GEVB also utilizes a simple but effective working principle, making it a safe, efficient, and reliable LED driving solution.
