AX2016/A 40V, 1.7A, Boost for 10 White LED Driver  GENERAL DESCRIPTION The AX2016/A is a step-up converter designed for driving up to 10 series white LEDs for backlighting application. The AX2016/A uses current mode, 1MHZ fixed frequency architecture to regulate the LED current, which is set through an external current sense resistor. Its low 300mV 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 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.  FEATURES 2.5V to 5.5V operating input voltage range Drives up to 10 series White LEDs 1MHz Fixed Switching Frequency Wide range for PWM dimming •yÑb€ (200Hz to 200KHz) R ` Internal 1.7A switching Ûmwcurrent limit om V Over Voltage Protection (OVP) h.c tec Internal Soft-start Function o f .go shutdown protection Current limit and Thermal w w Under voltage w Lockout Available in the 6-pin TSOT-23 and 8-pin TDFN Packages 1/11 Axelite Confidential Materials, do not copy or distribute without written consent.
