The AX2016 is a step-up converter designed for driving up to 10 series white LEDs for backlighting application. The AX2016/A/B uses current mode, 1MHZ fixed frequency architecture to regulate the LED current, which is set through an external current sense resistor. Its low 300mV/250mV/200mV feedback voltage reduces power loss and improves efficiency. The OV pin monitors the output voltage and turns off the converter if an over-voltage condition is present due to an open circuit condition. The AX2016/A/B includes under-voltage lockout, current limiting and thermal shutdown protection preventing damage in the event of an output overload. The driver is available in small 6-pin TSOT-23 and 8-pin TDFN (2mm x 2mm) packages.
