The MIC2282 is a boost LED driver optimized for single cell operation from alkaline, NiMH, or Li-Ion batteries. The MIC2282 operates with an input voltage between 0.9V to 15V, driving a string of series LEDs up to 33V. The combination of a low feedback voltage of 220mV and an operating current of 120µA provides a high efficiency solution that prolongs battery life.

The MIC2282 requires only five external components (diode, inductor, sense resistor, input capacitor, and output capacitor) to implement a low cost LED boost regulator. It is available in a compact 8-pin MSOP package with an operating range from -40°C to +125°C.
