The HV9910CSG-G is a mains dimmable LED controller that operates from an AC input voltage and provides an output voltage swing from 0 to 70V. It is a unit from the Power Management IC (PMIC) family that specializes in LED drivers. It includes a sophisticated accurate current control feature and is capable of delivering up to 1A LED driving current.

The main application field of the HV9910CSG-G involves providing a low cost, efficient and reliable LED driver. It can be used in a number of lighting systems, including low voltage LED lighting systems, residential lighting, commercial lighting and automotive lighting. In addition, it is suitable for powering other applications such as solenoid or motor controllers.

The HV9910CSG-G incorporates an advanced buck converter with pre-biased AC to DC power conversion and is designed to work with full range dimming (fades to zero). Its LED driving current can be accurately controlled, even at low dim levels (brightness), by using a step down converter. It features a wide dim curve that helps achieve smooth transitions from full brightness to minimum brightness. The device includes a comprehensive user interface and comprehensive programming features to adjust parameters such as driver current, voltage and dimming rate.

The working principle of the HV9910CSG-G is simple. The AC input is rectified and regulated to maintain a constant 0-70V output voltage. The output voltage\'s conduction is then regulated to generate a regulated current into the load (LEDs). The device also contains a safety circuit to protect it during fault conditions.

The device provides an efficient and reliable solution for driving multiple LEDs in a variety of applications. It is suitable for a wide range of operating environments and supports various dimming technologies. It is also capable of driving LEDs from 0.2W to 6W with a maximum output current of up to 1A.

The HV9910CSG-G provides an efficient and reliable LED solution for use in a variety of applications. Its state-of-the-art buck converter combines mains dimming, accurate current control, efficient power conversion and sophisticated user interface. With its wide dim curve, it facilitates smooth transitions from full brightness to minimum brightness levels. This makes it an ideal choice for LED lighting systems, residential lighting, commercial lighting and automotive lighting.
