Startup issues of DC/DC converters can be problematic, and even cause malfunction of the whole system. In this paper selected problems encountered during the DC/DC converter design process are described and solutions are provided. The first solution uses a modified driver, which limits the loading current during startup. The second solution uses a modified passive switch soft start, which based on linearly charged capacitance and output voltage detector with D flip-flop. The described solutions have been designed and fabricated using CMOS 110 nm technology.
