AS3691 LED Driver
4x400mA precision current source driving RGB and white color LEDs for general lighting
The AS3691 features four high precision current sources for driving up to four LED strings (RGB or single color leds). Each of the four currents sources can be controlled independently by PWM inputs. The full scale current value is set by external resistors.
- 4 x 400mA constant current outputs
- Programmable with external resistors
- 4 independent PWM inputs
- Absolute current accuracy ±0.5%
- Automatic Supply Regulation to reduce power dissipation
