General Description

The MIC2290 is a 1.2MHz , PWM, boost-switching regulator

housed in the small size 2mm × 2mm MLF™-8 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.

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.

The MIC2290 is available in a low-profile 2mm × 2mm

8-pin MLF™ leadless package and operates from a junction

temperature range of –40°C to +125°C.
