A8509 Datasheet | Allegro MicroSystems

Wide Input Voltage Range, High Efficiency 4-Channel Fault Tolerant LED Driver Features AND BENEFITS - Four integrated high current sinks for LED strings; can be tied together for even higher currents - Fixed frequency current mode control with integrated gate driver / boost controller; powerful gate driver to drive an external N-channel MOSFET allows significant scaling capability on the number of LEDs per string - Parallel operation with one boost controller (master) and up to three additional slave controllers; can run up to 16 strings of LEDs while populating only a single master boost regulator - Active current sharing between LED strings for 0.7% accuracy and 0.8% matching -...
