The MIC2250 is a general purpose DC/DC boost switching regulator that features low noise, EMI reduction circuitry, and high efficiency across a wide output current range. The MIC2250 is optimized for noise-sensitive hand held battery powered applications. A proprietary control method allows low ripple across the output voltage and current ranges. The MIC2250 incorporates a pseudo-random dithering function to reduce EMI levels up to 10dB enabled by the DITH pin.
