Integrated low-ripple fast-transient switching power converter with dynamic current compensation and sensor-free quasi-SCB hysteretic control
A low-ripple, fast-transient, switching power converter is presented in this paper. It employs a dynamic current compensation (DCC) technique to enhance load or dynamic voltage scaling (DVS) tracking transient responses. A sensor-free, quasi-single-current-band (quasi-SCB) control is proposed to obviate the use of large-ESR filtering capacitor in conventional hysteretic control, leading to highly reduced output voltage ripples. The converter was designed with a TSMC 0.35μm CMOS process. Its input voltage can vary from 2.7 to 3.3V while the output can be regulated at any voltage level from 0.5 to 1.8V, at a switching frequency of 500kHz. Compared with its conventional counterpart, the converter achieves 153 times and 15 times speed improvement on load transient and DVS tracking, respectively.
