Abstract :
Today and in the future, a huge market arises for mobile power . Efficient performance, functionality, small profile and low cost are the most desired features for mobile power management integrated circuits. Compared with the discrete-switching dc-dc converter, monolithic integration offers many benefits and new design challenges. In this paper, a monolithically integrated high-efficiency boost dc-dc converter for nickel metal hydride or alkaline battery-powered applications is designed based on the low-voltage CMOS process. Several novel concepts are proposed for compensator design, low-voltage startup, light-load efficiency and power device optimization.
