LED technology has been used increasingly in many different sectors due to its properties of providing bright and energy efficient light. However, to obtain the desired results from LED lighting, a proper power supply is essential which can be firstly provided by a PMIC – LED Driver. NCV3065MNTXG is one such LED driver which is designed for low power applications in industrial, automotive, and commercial lighting.

The NCV3065MNTXG is a cost-effective, highly efficient, buck-boost step-down regulator designed for low input voltage applications. It is capable of driving up to eight strings and features buck mode from 6V and boost mode from 2.2V. The steady frequency of 400 kHz and a wide input voltage range making it ideal for applications such as handheld devices, automotive lighting and industrial lighting where a low output voltage is required.

The main features of the NCV3065MNTXG are its integrated N-Channel MOSFET, low on-resistance (500mΩ at 4.5V VIN) and high spread of light intensity with the ability to adjust LED string voltage. Other features include built-in overvoltage protection and load disconnection, adjustable internal soft start and maximum operating frequency. The device also offers two temperature ratings that can reach 145°C: the package temperature can be used for applications with high temperature requirements and the junction temperature of the device can be used for applications with low temperature requirements.

The working principle of the NCV3065MNTXG is simple and straightforward. It starts with a low input voltage, typically up to 6V. The device regulates the output voltage through a buck-boost topology which regulates the output current for each LED string separately. To regulate the current, the device utilizes a voltage mode control system or peak current mode control system. The voltage mode control system regulates the current by setting a maximum voltage threshold and the peak current mode control system regulates the current by setting a peak current threshold. In addition, the device also uses pulse-skip mode under light load conditions to reduce power consumption.

The NCV3065MNTXG is suitable for industrial, automotive and commercial lighting applications, as well as handheld devices, due to its highly efficient power regulation and its low input voltage requirement. The device is popular because of its simple working principle, integrated N-channel MOSFET, wide input voltage range, adjustable soft start and maximum operating frequency, as well as its two temperature ratings that can reach 145°C. With its features and advantages, the NCV3065MNTXG can provide a reliable, cost-effective, and energy efficient way to power LEDs in a wide range of applications.
