Abstract :
A 100 MHz digitally assisted 4-phase switched-inductor boost converter delivers 240 mW to load voltages of 3 to 5 V with peak efficiency of 64%, and a 45 MHz hybrid switched-inductor/capacitor boost converter delivers 20 mW over a 6 to 10V output range at peak efficiency of 37%. Implemented in a standard 1.2 V 0.13 μm CMOS, the converters use integrated schottky diode rectifiers with 10 V blocking voltages for DCM switching.
