The MIC2290 is a 1.2MHz , PWM, boost-switching regulator. 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. The MIC2290 implements a constant frequency 1.2MHz PWM control scheme. The high frequency operation saves board space by reducing external component sizes. The fixed frequency PWM topology also reduces switching noise and ripple to the input power source. The MIC2290's wide 2.5V to 10V input voltage allows direct operation from 3- to 4-cell NiCad/NiMH/Alkaline batteries, 1- and 2-cell Li-Ion batteries, as well as fixed 3.3V and 5V systems.
