Application Type: LED Driver Evaluation
Core Supported: AS3691
Features & Applications

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.

Key Features :

  • 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              1)  Patent Pending
  • Very wide output voltage current source voltage compliance Down to 0.41V up to 15V 2)
  • Integrated overtemperature protection
  • Separate sense pads (Rfb1-Rfb4) for easy and precise PCB Layout
  • Package QFN24 4x4mm
    2) 15V is sufficient for most applications as the AS3691 dose not switch off the LED current completely

Application :

  • General Lighting
  • Backlighting
  • RGB Backlighting for LCD TV/Monitors with White Color Balancing
