Micrel, Inc.  
MIC2288  
1A 1.2MHz PWM Boost Converter in  
Thin SOT-23 and 2×2 MLF™  
General Description  
Features  
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.  
• 2.5V to 10V input voltage range  
• Output voltage adjustable to 34V  
• Over 1A switch current  
• 1.2MHz PWM operation  
• Stable with ceramic capacitors  
• High-efficiency  
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  
spuriousswitchingnoiseandrippletotheinputpowersource.  
• <1% line and load regulation  
• Low input and output ripple  
• <1µA shutdown current  
• UVLO  
• Output overvoltage protection (MIC2288BML)  
• Over temperature shutdown  
• Thin SOT-23-5 package option  
• 2mm × 2mm leadless MLF™-8 package option  
• –40°C to +125°C junction temperature range  
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.  
Applications  
The MIC2288 has a junction temperature range of –40°C to  
+125°C.  
• Organic EL power supply  
• TFT-LCD bias supply  
All support documentation can be found on Micrel’s web  
site at www.micrel.com.  
• 12V supply for DSL applications  
• Multi-output DC/DC converters  
• Positive and negative output regulators  
• SEPIC converters
