Control of DC-DC Converters
multi-phase buck converter, interleave technique, adaptive on-time, fast transient response
Without any user predefined load transient threshold voltage, the proposed technique can automatically turn on two phases immediately. Besides, an adaptive-extended TON control (AETC) mechanism is adopted to overcome the steady-state switching frequency variation without shrinking the on-time compare to the conventional adaptive on-time (AOT) methodology. A CMOS dual-phase buck converter is realized in a 0.18um process to verify these two techniques.
