MIC2807
RF PA Power Management IC 2MHz, 600mA DC/DC w/DAC Input and
Bypass Switch, Dual Low Noise 200mA/30mA LDO Regulators
General Description
The MIC2807 integrates a high performance 600mA DC/DC converter intended for powering a power amplifier (PA) in a mobile phone with dual low noise low dropout (LDO) regulators for the rest of the RF section.
Optimized for low noise performance, the MIC2807 improves efficiency in the handset without compromising quality.
The MIC2807 has a 2MHz, constant frequency pulse width modulated (PWM) DC/DC converter designed for low noise operation and high efficiency.
