MIC2282
Single-Cell Ultra Low EMI Boost LED Driver
General Description
The MIC2282 is a boost LED driver optimized for single cell operation from alkaline, nickel-metal-hydride, or lithium 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...
