一种快速响应高效多模式升压降压型转换器
Rapidly transient response with the flexible mode and high-efficiency buck-boost converter
摘要
Abstract
A novel current sensing technique with a rapidly transient and flexible mode buck‐boost converter is presented . The converter can work in an appropriate mode according to the input voltage ( VIN ) and inductor current ( IL ) , with smooth transition and flexible working modes achieved . The average current sensing ( AVCS ) circuit has an accurate measurement of IL . The transient response time is also decreased . The current sensing converter is implemented in the Silterra 0.18μm COMS process . Experimental results show 95% peak efficiency at an output current 1 A with 4.2 V VIN , so that the converter can extend the battery life . The output transient with the load current altering from 0 to 2 A is 6 mV and the recovery time is 60μs .关键词
