Abstract :
A single-inductor 6-channel regulated output DC-DC buck converter employing PLL-based multiple-output bang-bang (PMB) control is presented. A mixture of comparator control and bang-bang control is used for regulating the multiple output channels inside the PLL loop. The fabricated chip occupies 2.5 × 3 mm2 in a 0.35 ¿m CMOS process with a switching frequency of 2 MHz.
