A high-efficiency hysteresis buck converter using auto selectable frequency-locked techniques
A high-efficiency wide workload hysteresis buck converter using auto selectable frequency-locked techniques is designed with the TSMC 0.18-μm 1P6M process. The proposed buck converter yields fast-response by using hysteresis control. The workload range, power efficiency, and EMI noise problem are improved by auto-selectable frequency and frequency-locked techniques. The selected switching frequency is determined with load current. Simulation results show that this buck converter's switching frequency is locked at four frequencies for the load current between 10 and 400mA: 250k, 500k, 1M, and 2MHz. Furthermore, it achieves more than 90% power efficiency over 95% of the load range, with a peak efficiency of 96.27%.
