With the development of application processors in mobile device, the power supply is required to have high current driving capability and low standby power consumption. In this paper, a novel dual-phase DC-DC buck converter with low quiescent consumption is proposed to meet the demand. Apart from conventional PWM/PFM mixed control, an extra power-save mode (PSM) is designed in the converter to minimize...
A novel current mirror sensing based multi-phase current balance developed in Global Foundry 0.18μm CMOS process was presented in this paper. Different from conventional current mirror sensing method, a new bypass branch was added to make the sample signal more accurate in high switching frequency situation. The method was realized in a 2.5MHz four-phase buck converter. As the simulation result shows,...
