Summary

The MIC2250, a high efficiency, low EMI boost regulator is optimized for noise sensitive hand held battery powered applications. The proprietary control method allows low ripple across the output voltage and current ranges. Additionally, the MIC2250’s DITH function introduces a pseudo-random dithering of the switching frequency to reduce EMI levels by up to 10dB. The MIC2250 operates from an input voltage range of 2.5 to 5.5V. This board enables the evaluation of the MIC2250, a fully integrated, general purpose boost regulator with high efficiency over a wide load range. The board includes jumpers to allow manual setting of enable and dither functions.
