General Description
The MIC2288 is a 1.2MHz PWM, DC/DC boost switching regulator available in low-profile Thin SOT-23 and 2mm × 2mm MLF™ package options. High power density is achieved with the MIC2288’s internal 34V/1A switch, allow ing it to power large loads in a tiny footprint.
The MIC2288 implements a constant frequency, 1.2MHz PWM, current mode control scheme with internal compensation that offers excellent transient response and output regulation performance. The high frequency operation saves board space by allowing small, low-profile, external components. The fixed frequency PWM topology also reduces spurious switching noise and ripple to the input power source.
The MIC2288 is available in a low-profile Thin SOT-23-5 package and a 2mm × 2mm MLF™-8 leadless package. The 2mm × 2mm MLF™-8 package option has an output over voltage protection feature.
