MIC2250
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.
The MIC2250 is designed for use with inductor values from 4.7µH to 22µH, and is stable with ceramic capacitors from 1µF to 22µF.
The MIC2250 attains a high peak efficiency up to 90% at 100mA and excellent light load efficiency of 80% at 1mA.
High power density is achieved with the MIC2250's internal 34V/2A rated switch, allowing it to power large loads in a tiny footprint.
The MIC2250-1 is available in a 5-pin Thin SOT-23 package with dithering disabled. While the MIC2250-2 is available in a 5-pin Thin SOT-23 package with dithering enabled. The MIC2250 is available in 8-pin 2mm x 2mm MLF® leadless package option with an operating junction temperature range of -40°C to +125°C.
