NCV78247V1NOLEDEVK, which stands for N ovel C onverter V ectored 78247V1 NOLEDEVK, is an integrated solution for lighting control systems and energy metering applications. It is a highly integrated DC-DC buck/boost converter with a 2-channel dimming channel designed for LED lamp applications. It includes dedicated on-chip functions for ambient light sensing, power monitoring, and thermal protection. It can be used for lamp system control, precise power regulation, and dimming solutions.

The application fields of NCV78247V1NOLEDEVK can be divided into four main categories:

Consumer Lighting Applications: This power converter is ideal for the development and evaluation of lighting systems, such as energy-saving LED lamps or home lighting. It enables the rapid development of precision and highly efficient LED lamp solutions.

Commercial Lighting Applications: By taking advantage of its thermal overshoot protection, the NCV78247V1NOLEDEVK is very suitable for commercial lighting applications that require high quality and precision, such as hospitality lighting and office lighting. The device supports a wide range of dimming protocols such as 0 ~ 10 V and 1 ~ 10 V.

Industrial Lighting Applications: Industrial lighting applications require the dimming of high power LED lighting fixtures with high efficiency. The NCV78247V1NOLEDEVK has a high-efficiency integrated switch mode power converter, which supports a wide dimming range and can be used with various dimming protocols. It also has an ambient light sensing function, which makes it possible to adjust the brightness intelligently by sensing the ambient light.

Automotive Lighting Applications: Automotive lighting applications require high efficiency, low noise, and low cost. The NCV78247V1NOLEDEVK offers all these features for automotive lighting applications. It supports a wide range of dimming protocols and can be used in various applications such as outdoor lighting, interior lighting, and vehicle indicators.

The working principle of NCV78247V1NOLEDEVK is based on the buck-boost converter circuit. The device is designed with a topology consisting of two stages: the first stage is the buck stage and the second stage is the boost stage. The buck stage is a high-efficiency boost converter that steps down the input voltage to a lower output voltage. The boost stage then boosts the output voltage to a higher voltage. An integrated overvoltage protection circuit is in place to protect the converter from overvoltage conditions.

The device integrates two channels of dimming interfaces. The dimming channel accommodates the input of a 0 to 10 V dimmer signal, which is used for dimming the LED lamps. A 1 kHz clock is also integrated to provide the timing signal to control the dimming channel. The device also provides overvoltage and thermal protection for the dimmer circuit.

NCV78247V1NOLEDEVK provides a robust and highly efficient solution for various lighting applications. It has a wide range of applications in consumer lighting, commercial lighting, industrial lighting, and automotive lighting. It provides a high-efficiency, low-noise, and cost-effective dimming solution for LED lamps, and supports various dimming protocols such as 0 ~ 10 V or 1 ~ 10 V. It also has an integrated ambient light sensing function and integrated thermal protection for enhanced safety and reliability.
