MIC2203  
High Efficiency 1MHz Synchronous  
Buck Regulator  
General Description  
Features  
The Micrel MIC2203 is a high efficiency 1MHz PWM  
synchronous buck switching regulator. The MIC2203  
features low noise constant frequency PWM  
operation with a low dynamic supply current of  
<1mA. The low noise and efficient operation both  
make the MIC2203 well suited for sensitive RF, and  
audio power applications.  
Input voltage range: 2.3V to 5.5V  
Output voltage adjustable down to 0.5V  
300mA output current  
Constant 1MHz PWM switching frequency  
> 95% efficiency  
< 1mA switching supply current  
< 350µA static quiescent current  
< 1µA shutdown current  
The MIC2203 operates from 2.3V to 5.5V input and  
can supply over 300mA of output current with output  
voltages down to 0.5V. Additionally, the MIC2203  
can be synchronized to an external clock, or multiple  
MIC2203s can easily be daisy-chained with the  
SYNCLOCK feature.  
All-ceramic capacitors  
Easily synchronized to external clock  
SYNCLOCK feature to daisy chain multiple  
devices  
The MIC2203 has a high loop bandwidth with  
corresponding ultra fast transient response times.  
This reduces the output capacitor size, and is very  
useful when powering applications that require fast  
dynamic response such as CPU cores and RF  
circuitry in high performance cellular phones and  
PDAs.  
Thermal shutdown and current limit protection  
10 pin MSOP, and 3mm x 3mm MLF-10L package  
options  
–40ºC to +125ºC junction temperature range  
Applications  
The MIC2203 is available in 10-pin MSOP and  
3mm x 3mm MLF™-10L package options with an  
operating junction temperature range from –40ºC to  
125ºC.
