升压式DC/DC的软启动电路的设计
The Design of Boosting Voltage DC/DC Soft-Star Circuit
摘要
Abstract
Based on BiCMOS,a kind of boosting voltage DC/DC pulse-charging soft-star circuit was presented.The small proportion of hold and empty (0.1%) of soft-star capacitance charged was realized using dividing frequency circuit and short-pulse producing circuit Without using exterior capacitance,the circuit ensures the enough time of soft starting and eliminates the surging phenomena.HSPICE simulation proves that the circuit can spend small capacitance (10 pF)to realize the long soft-star process (800 pis).关键词
