MIC2251YML-TR Power Management ICs - PMIC by Microchip Technology
1.6A Isw Low EMI Boost Regulator w/Dithering
| Status: | Active |
|---|---|
| Series: | MIC2251 |
| RoHS: | Compliant |
The MIC2251 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 MIC2251 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 MIC2251 incorporates a pseudo-random dithering function to reduce EMI levels up to 10dB enabled by the DITH pin. The MIC2251 is designed for use with inductor values from 4.7µH to 22µH, and is stable with ceramic capacitors from 1µF to 22µF. The MIC2251 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 MIC2251's internal 40V/2A rated switch, allowing it to power large loads in a tiny footprint. The MIC2251-1 is available in a 5-pin Thin SOT-23 package with dithering disabled. While the MIC2251-2 is available in a 5-pin Thin SOT-23 package with dithering enabled.
