AOZ1083 Datasheet | Alpha & Omega Semiconductors

1.2 A Buck LED Driver General Description The AOZ1083 is a high efficiency, simple to use, 1.2 A buck HB LED driver optimized for general lighting applications. The AOZ1083 operates from a 3 V to 26 V input voltage range and provides up to 1.2 A of continuous LED current. The 280 mV LED current feedback voltage minimizes the power dissipation of the external sense resistor. The fixed switching frequency of 1.5 MHz PWM operation reduces inductor and capacitor sizes. The AOZ1083 is available in a tiny SOT23-6L package.
