General Description

The MIC2290 is a 1.2MHz, PWM, boost-switching regulator housed in the small size 2mm × 2mm 8-pin MLF® package. The MIC2290 features an internal Schottky diode that reduces circuit board area and total solution cost. High power density is achieved with the MIC2290’s internal 34V/0.5A switch, allowing it to power large loads in a tiny footprint.
