The NCV3066DR2G is a power management integrated circuit (PMIC) designed specifically as a LED driver. It is a current-mode PWM controller with an integrated high-side switch, allowing it to control the current of the LED from either a current-based PWM signal or an external voltage. It is capable of driving up to 800mA of LED current and has an LED open/short protection that prevents LED destruction in the event of a fault. The NCV3066DR2G is also designed to reduce the number of support components needed when driving LEDs and boasts fairly low power consumption.

The NCV3066DR2G can be used in many applications, such as high power or automotive lighting, general lighting and sometimes even industrial applications. Its many features make it suitable for this variety of applications, as it can be used to directly drive LEDs with high precision, while still providing the level of protection needed for those types of applications. It also supports a variety of input sources, making it ideal for systems that require power from different sources. Additionally, the NCV3066DR2G has an integrated over-temperature protection, which can provide extra safety and reliability when controlling the LED current.

When using this device, it is important to note that its maximum output current is 800mA. To achieve this, it carries an internal N-channel MOSFET, which is used to control the LED current by varying the voltage of either a continuous voltage from the input sources or a PWM signal from a controller. The internal MOSFET can be used to operate either in the continuous current mode or the discontinuous current mode for more efficient power usage.

The NCV3066DR2G also includes several features to provide extra protection from overloads and short circuits. One of the main features is the open/short LED protection, which prevents the LED from being destroyed in the event of a fault. The device also carries a soft-start function, which reduces in-rush current on power up, plus a thermal overload protection feature and an over voltage protection circuit.

Overall, the NCV3066DR2G can be used in many different applications, thanks to its versatility and robust protection features. It is a great choice for anyone who needs to control the LED current with high accuracy and reliability. Its low power consumption and the many features that reduce the support components needed to drive the LEDs make it a popular choice. Needless to say, this PMIC is an excellent choice for driving LEDs in a wide range of applications.
