A Novel Current-Mode Boost Converter with Depletion-Mode MOSFET
A compact current-mode boost converter for battery-operated portable devices is presented in this paper. With the help of depletion-mode MOSFET, the chip’s volume reduces and input voltage extends from 2.5V to 10V. Using a 0.5μm BCD process, the maximum efficiency of this converter can reach 90％ at fixed frequency 1.4MHz. In addition, a single input error amplifier and dead-time control circuit for this design are proposed in the paper. The simulation results and measures verify the function of the proposed structure.
