MIC2224 Datasheet (Micrel Semiconductor) - High Efficiency 2MHz PWM Buck Converter

MIC2224, High Efficiency 2MHz PWM Buck Converter

The MIC2224 is a high efficiency 2MHz PWM synchronous buck switching regulator optimized for powering 2.5G and 3G CDMA RF Power Amplifiers.

The output voltage of MIC2224 can be dynamically adjusted with an external DAC to maximize PA efficiency versus required output power.

When the PA requires the
