Abstract :
The Earth is mobile. There is a huge market for mobile power nowadays and in the near future. Efficient performance, functionality, small profile and low cost are the most wanted features for mobile power management ICs. In this work, A high-efficiency, high frequency, wide input range monolithic step down DC-DC converter ASIC is designed, based on advanced trench BCD technology. Several novel control concepts are proposed to improve the stability efficiency and transient response. Some important design issues such as device optimisation, driver speed design, parasitic component effects and compensation design are elaborated in this paper.
