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.
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.

Output voltage adjustable down to 0.5V
300mA output current
Constant 1MHz PWM switching frequency
> 95% efficiency
< 1mA switching supply current
< 350 μ A static quiescent current
< 1 μ A shutdown current
All-ceramic capacitors
Easily synchronized to external clock
SYNCLOCK feature to daisy chain multiple
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.
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.
