AX2012 Description
The AX2012 is a step-up converter designed for driving up to 8 series white LEDs for backlighting application. The AX2012 uses current mode, 1.2MHZ 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.
