摘要
To satisfy today's power demands of a VLSI chip, the digital power IC has been designed in order to have more programmability, faster transient response and higher efficiency. Thank to the advance of the semiconductor manufacturing process. It has enabled the ability to integrate the power MOSFET, the analog and the digital circuits into one chip. In this paper, a 12V, 2A digital synchronous DC-DC buck converter IC with the nonlinear control (NLC) to improve the transient response and the pulse-skipping mode (PSM) to improve the power conversion efficiency has been designed and fabricated. The I2C is provided to let the host controller in-situ program and monitor the operating conditions of the IC. Both the loading current and the operating mode transient response of the IC have been demonstrated.
