Introduction to AS3683

The AS3683 is a General Purpose LED Driver, which is an integrated lighting solution suitable for automotive, industrial and consumer applications. It is based on advanced white-light LED current regulation, and is designed to provide high accuracy brightness control for LEDs in automotive and consumer electronics products. The AS3683 has a flexible architecture that allows for a wide range of applications, from stand-alone white-light LED driving applications to multiple-channel RGB systems, where it controls up to 6 channels.

Installation and Connection

The AS3683 is a standalone LED driver which can be integrated directly into a lamp or other lighting fixture. The module includes two external connections, one positive input power line and one return line. The input voltage range is 8-20V. The AS3683 requires only 5 connections to a microcontroller or processor, with no external loop resistors necessary. Depending on the application, the AS3683 has 2 modes available: LED output current or LED brightness control.

Application Field of AS3683

The AS3683 is primarily designed for automotive, industrial and consumer applications. For example, the AS3683 can be used in lighting certification systems in which strict accuracy and dimming requirements must be met. Additionally, the AS3683 is suitable for various automotive applications such as daytime running lights, fog lamps, indicator and position lights and head lights. The AS3683 is also suitable for industrial and consumer applications such as emergency lights, nightlights and landscape lighting. In these applications, the AS3683’s precision dimming control enables high performance and consistent brightness with low power consumption.

Working Principle of AS3683

The AS3683 is a hybrid step-down buck and boost LED driver, using current regulation to control the brightness of LEDs. It incorporates switch mode regulators to maintain a constant current, compensates for voltage variations, and offers good dimming performance with minimal power losses. The AS3683 has a single or dual inductor design, depending on the application. In the single inductor design, a boost regulator is used for driving the LED with a particular current. In the dual inductor design, a current source output is used, where the brightness of the LEDs is controlled by the resistor value. The AS3683 can also be used to drive multiple channels of LEDs. In this case, the load sharing is performed automatically and the output currents are balanced across each channel.

Conclusion

The AS3683 is a highly integrated LED driver offering a highly flexible solution for a wide range of applications. The configurable input voltage range and selectable single or dual inductor design make it suitable for automotive, industrial and consumer LED lighting applications. The AS3683 features high efficiency operation, precision dimming control and current regulation, and can be used in multiple-channel RGB systems.
