MIC23051  
4MHz PWM Buck Regulator with  
HyperLight Load™ and Voltage Scaling  
General Description  
Features  
The Micrel MIC23051 is a high efficiency 600mA PWM  
synchronous buck (step-down) regulator featuring  
HyperLight Load™, a patented switching scheme that  
offers best in class light load efficiency and transient  
performance while providing very small external  
components and low output ripple at all loads.  
• Input voltage: 2.7V to 5.5V  
• 600mA output current  
• Fixed output voltage from 0.72V to 3.3V  
• Output voltage scaling option  
• Ultra fast transient response  
HyperLight Load™  
• 20µA typical quiescent current  
• 4MHz in CCM PWM operation in normal mode  
• 0.47µH to 2.2µH inductor  
The MIC23051 has an output voltage scaling feature that  
can toggles between two different voltage levels.  
The MIC23051 also has a very low typical quiescent  
current draw of 20µA and can achieve over 85% efficiency  
even at 1mA. The device allows operation with a tiny  
inductor ranging from 0.47µH to 2.2µH and uses a small  
output capacitor that enables a sub-1mm height solution.  
• Low voltage output ripple  
–
–
25mVpp in HyperLight Load mode  
3mV output voltage ripple in full PWM mode  
• >93% efficiency  
• ~85% at 1mA  
In contrast to traditional light load schemes HyperLight  
Load™ architecture does not need to trade off control  
speed to obtain low standby currents and in doing so the  
device only needs a small output capacitor to absorb the  
load transient as the powered device goes from light load  
to full load.  
• Micropower shutdown  
• Available in 8-pin 2mm x 2mm MLF®  
• –40°C to +125°C junction temperature range  
At higher loads the MIC23051 provides a constant  
switching frequency of greater than 4MHz while providing  
peak efficiencies greater than 93%.  
Applications  
• Cellular phones  
The MIC23051 is available in fixed output voltage options  
from 0.72V to 3.3V eliminating external feedback  
components. The MIC23051 is available in an 8-pin 2mm x  
2mm MLF® with a junction operating range from –40°C to  
+125°C.  
• Digital cameras  
• Portable media players  
• Wireless LAN cards  
• WiFi/WiMax/WiBro modules  
• USB Powered Devices
