RoHS: | Compliant |
The 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.
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 package with an operating junction temperature range from -40°C to 125°C.
