- W4320005194 abstract "Abstract Due to the progress of science and technology and the rapid development of the economy, human performance requirements for electronic products are getting higher and higher. Therefore, it is necessary to study a Boost-type DC-DC converter with high conversion efficiency, miniaturization, strong stability, and fast start speed. Currently, there are many ways to solve the DC-DC switching power supply problem. By analyzing the switching power supply, an efficient digital soft start method for boosting DC-DC switching power supply. This method adopts programmable digital technology. By precharging the output capacitor with the multiplexed substrate switching circuit, the output current rises steadily, and the soft start effect of the switching power supply is achieved. Based on the 0.18um BCD process, the test shows that when the input voltage is 3.7 V, the output voltage is 4.6 V, and the duty ratio is 20%, the soft start time is 210 us when the PVT changes and the steady rise of the output voltage does not produce the surge current phenomenon. Through theoretical analysis and experimental verification, the proposed method has the obvious advantages of simple structure, strong stability, low power consumption, and fast starting speed." @default.
