Abstract :
A dual-phase digital PWM controller is presented for DC-DC switching converters. This controller not only regulates the output voltage of a DC-DC converter, but also provides current balancing for the dual-phase power converter. By using voltage-current reaction current balancing, the system complexity is reduced. The chip has been fabricated in 0.35mum CMOS process and the active area is 1.996mm2. It consumed 40mW from a 3.3V supply
