摘要
The earth is mobile. There is a huge market for mobile power management lCs today and in the future Ill. Fast transient response, efficient performance, small profile and low cost are the most desired features for mobile power management IC. In this paper, a 2MHz high efficiency, wide input range monolithic buck DC-DC converter ASIC is designed based on advanced trench BCD process. Some important design issues such as compensator design for wide range of input, output voltage and load current, linear-nonlinear control for fast transient response, efficiency optimisation, device optimisation, noise separation and driver design are discussed. The experiment test results show that the ASIC works well.
