Micrel MIC2807
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.| Part No. | MIC2807 |

GENERAL DESCRIPTION
The output voltage (VOUT) is variable from 0.3V to the input voltage (VIN), adjustable from 0.3V to 3.6V through a DAC input when VIN > VOUT. The converter will work in a 100% duty cycle mode to offer maximum power and efficiency in the application. In addition to 100% duty cycle, the DC/DC converter has a bypass mode of operation where the input voltage node (PVIN pin) is shorted to the o
