Abstract :
The earth is mobile. There is a huge market for mobile power today and in the future. Efficient performance, functionality, small profile and low cost are the most wanted features for mobile power management ICs. Compared with the discrete switching DC-DC converter, monolithic integration brings a lot of benefits and new design issues. In this work, a monolithic low voltage high efficiency step-up DC-DC converter for nickel metal hydride or alkaline battery powered applications is designed, based on a low voltage CMOS process. Several novel design concepts are proposed for compensator design, low voltage startup, light load efficiency and power device optimization.
