A Monolithic Current-Mode Buck Converter With Advanced Control and Protection Circuits

Autor: Wei-Zen Chen, Jiin-Chuan Wu, Feng-Fei Ma

Publikováno v: IEEE Transactions on Power Electronics. 22:1836-1846

A monolithic current-mode pulse width modulation (PWM) step-down dc-dc converter with 96.7% peak efficiency and advanced control and protection circuits is presented in this paper. The high efficiency is achieved by "dynamic partial shutdown strategy

Advanced Control and Protection Techniques for DC-DC Switched Mode Power Supply IC Design

Autor: Feng-Fei Ma, 馬鳳飛

95
In this dissertation, we discuss about the switched mode power supply (SMPS) for DC-DC power conversion. Basic topologies of non-isolated DC-DC SMPS are introduced. Safety considerations for power supply design are discussed. The design speci
