ALLEGRO A8516 multi-output WLED/RGB driver is a versatile LED driver IC that reduces component count and overall system cost. Device integrates a boost controller to drive an external MOSFET and six internal current sink channels capable of up to 80mA each, and channels can be combined together to achieve even higher currents. The boost converter operates in constant frequency (programmable) current mode control. The LED sink current is set by an external R_ISET resistor and PWM dimming allows LED currents to be controlled.
