    High Efficiency 2MHz PWM Buck Converter with
    DAC Input and 40mΩ Bypass Switch General Description Features 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 highest power, the DAC
    can be used to enable a low on-resistance, 40mΩ, bypass
    switch that powers the PA directly from the battery.
    The 2MHz PWM operation of MIC2224 allows the smallest
    possible components. It also allows the device to easily
    meet stringent W-CDMA VOUT response specifications.
    The MIC2224 operates from a 2.7V to 5.5V input, making
    it ideal for single cell Li-Ion applications. The device
    features built-in power MOSFETs that can supply up to
    600mA of output current in PWM mode, or over 1A in
    bypass mode. The MIC2224 can operate with a maximum
    duty cycle of 100% for use in low-dropout conditions.
    The MIC2224 has a junction temperature range of
    –40°C to +125°C and is available in a 10-pin 3mm x 3mm
    MLF® package.
