The FAN7710VLN is a low voltage lighting ballast controller integrated circuit (IC) that control integrated LED lamps and LED drivers in LED light fixtures. It is a part of a family of companion ICs developed by Fairchild Semiconductor. This IC is capable of operating up to 4 LEDs with single terminal voltage drive and provides current limiting and separately adjustable dimming. It also provides system cost savings by eliminating the need for a dedicated current limit resistor.

The FAN7710VLN features a single-terminal, low-voltage, digital inrush current limiter (DICL) mode. It can operate up to 4 LEDs with the same single-terminal voltage. This IC also provides dimming with separate control for each of the LEDs. In addition, it comes with a slew rate control circuitry to minimize inrush current. The operating temperature range is from -40°C to +105°C.

The FAN7710VLN takes in the input voltage ranging from 5V to 30V and the dimming current can be programmed to the desired maximum value. The voltage programming pins can be used to program the maximum dimming current for each LED. The current limit is applied based on the programmed dimming current, and the LED voltage will be regulated based on the dimming current.

The FAN7710VLN implements cycle-by-cycle current limiting. During normal operation, the current sense voltage rises linearly with increasing LED voltage. When the programmed dimming current is reached, current limiting is triggered and the voltage of the LED will be regulated at the programmed dimming current. When the overload conditions are detected, the current limiting is automatically triggered. The operating temperature range for FAN7710VLN is from -40°C to +105°C.

The FAN7710VLN is ideal for low-voltage lighting applications such as LED lamps and drivers used in home, hotel and other hospitality areas. It can be used in lighting applications such as table lamps, automotive interior lighting, accent lighting, and accent over-lighting. The IC is also suitable for other applications such as power converters, ballast lighting systems, conveyors, and displays.

The FAN7710VLN is widely used in applications where dimming, power control, and energy efficiency are crucial. It is a cost-effective solution that allows for increased current levels and power savings, as well as long lifetime and minimal maintenance. The IC also provides protection against electrical overstress, over voltage, and over-current.
