PMIC (Power Management Integrated Circuit) is an essential device for the power-supply management and protection of modern electronic equipment. The NCV7684DQR2G series is a high-performance PMIC device specifically developed for LED lighting applications. It is a monolithic device that integrates multiple power functions, including LED driver, power switch and current sensor into a single chip, with a voltage output range of 5V to 65V.

The NCV7684DQR2G is a high-efficiency, three-channel, step-down PMIC designed specifically for driving a variety of power LEDs in both lighting and signage applications. It offers excellent flexibility in terms of choice of both the dimming range and the number of LEDs being driven. The device utilizes both analog and Pulse Width Modulation (PWM) dimming as required by the application. The device integrates an over-voltage protection circuit, providing extra safety to the system.

The working principle of the NCV7684DQR2G is simple and effective. The input voltage is converted by the internal high-efficiency power converter blocks and is then distributed to the LED channels. The LED channel current is regulated by the LED current regulators and can be modulated for dimming purposes. A digital pulse-width modulation (PWM) dimming pin is also provided that enables digital dimming. The device also includes precision level shifting and an output enable feature for additional flexibility.

The key features of the NCV7684DQR2G include:

• High efficiency (up to 97%): allows the system to run cooler and save energy.
• Multiple LED outputs: supports up to 3 independent LED channels.
• Dimming options: multiple dimming options are available, including analog, pulse-width modulation, and digital dimming.
• Integrated protection functions: over-voltage, over-current, and thermal protection.
• Wide input voltage range (5V to 65V): can handle both low and high voltages safely.
• High-output accuracy: ensures the total output current accuracy for all channels.

The wide input voltage range and efficient output accuracy of the NCV7684DQR2G make it suitable for a variety of applications, from high-power LED lighting systems to automotive headlight and taillight applications. It can also be used in a variety of outdoor LED display applications. Thus, the NCV7684DQR2G offers a reliable, cost-effective, and highly efficient power management solution for LED lighting and signage applications.
