Robust Multiple-Phase Switched-Capacitor DC-DC, Converter with Digital Interleaving Regulation Scheme
An integrated switched-capacitor (SC) DC-DC converter with a digital interleaving regulation scheme is presented. By interleaving the newly-structured charge pump (CP) cells in multiple phases, the input current ripple and output voltage ripple are reduced significantly. The converter exhibits excellent robustness, even when one of the CP cells fails to operate. A fully digital controller is employed with a hysteretic control algorithm. It features dead-beat system stability and fast transient response. Hspice post-layout simulation shows that, with a 1.5 V input power supply, the SC converter accurately provides an adjustable regulated power output in a range of 1.6 to 2.7 V. The maximum output ripple is 40 mV when a full load of 0.54 W is supplied. Transient response of 1.8 mus is observed when the load current switches from half- to full-load (from 100 to 200 mA)
