晒WEBENCH设计的过程+转换电压的设计 [复制链接]

发现用这个设计工具最大的设计手段就是电压的转换了，可以得到很多的转换细节，比如多少电压转多少电压，直流交流之间的转换，升压和降压，以及更复杂的设计，都可以做的很好，目前看，主要还是转换电压最方便，比如DC-DC的逆变，输入2.7V， 输出使用5V基准电压，电流采用很小的0.33A，环境温度设置在30度， 保持低温，以求得效率的不升温，芯片采用LM2735，The LM2735 is an easy-to-use, space-efficient 2.1A low-side switch regulator ideal for                 Boost and SEPIC DC-DC regulation. It provides all the active functions to provide local DC/DC                 conversion with fast-transient response and accurate regulation in the smallest PCB area. Switching                 frequency is internally set to either 520kHz or 1.6MHz, allowing the use of extremely small surface                 mount inductor and chip capacitors while providing efficiencies up to 90%. Current-mode control and                 internal compensation provide ease-of-use, minimal component count, and high-performance regulation                 over a wide range of operating conditions. External shutdown features an ultra-low standby current                 of 80 nA ideal for portable applications. Tiny SOT-23, WSON, and MSOP-PowerPAD packages provide                 space-savings. Additional features include internal soft-start, circuitry to reduce inrush current,                 pulse-by-pulse current limit, and thermal shutdown.以上是对芯片的英文描述。采用自动优化，
