MIC2288
1A 1.2MHz PWM Boost Converter in
Thin SOT-23 and 2
×
2 MLF
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 compensa-
tion that offers excellent transient response and output regu-
lation performance. The high frequency operation saves
board space by allowing small, low-profile, external compo-
nents. 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.
The MIC2288 has a junction temperature range of –40
°
C to
+125
°
C.
