AOZ1084 1.2A Buck LED Driver General Description The AOZ1084 is a high efficiency, simple to use, 1.2A buck HB LED driver optimized for general lighting applications. The AOZ1084 works from a 4.5V to 36V input voltage range, and provides up to 1.2A of continuous LED current. The 160mV LED current feedback voltage minimizes the power dissipation of the external sense resistor. The fixed switching frequency of 450kHz PWM operation reduces inductor and capacitor sizes. The AOZ1084 is available in a tiny DFN2x2-8L package. Features  Up to 36V operating input voltage range  420mΩ internal NMOS  Up to 95% efficiency  Internal compensation  1.
