AX2016

40V, 1.7A, Boost for 10 White LED Driver



GENERAL DESCRIPTION

The AX2016 is a step-up converter designed for driving up to 10 series white LEDs for

backlighting application. The AX2016 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 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 SOT-23 package.
