AOZ1084DI

AOZ1084DI

EZBuck™ DC-DC Buck Regulators

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 its 450kHz PWM operation enables the use of smaller inductor and capacitor sizes.
