|---|---|---|
To meet the demands of modern mobile devices on higher current and longer standby time, a novel high driving capability multi-phase interleaved buck converter with low standby power consumption is proposed. By transferring the control scheme from adaptive-on-time (AOT) mode to pulse-frequency-modulation (PFM) mode, the efficiency at light load could be improved. Phases can automatically shed to minimize the power consumption of the controller. The proposed control scheme was verified on an integrated 2.5 MHz switching frequency four-phase-interleaved DC-DC synchronous buck converter with 5.5-2.5 V input and 1.5-0.5 V output, using 0.18 μm Global Foundry BCD technology. Simulation results showed that the maximum output current could be 16 A. The current consumption of the controller was reduced by up to 72% at light load condition and the standby quiescent current was 7 μA. |
