DCDC电源变换器的设计和制作

开关变换情况下,电源输出电压要求28VDC/0.15A 纹波小于等于0.28Vpp5vdc/0.6A 纹波小于等于0.5Vpp电压调整率小于等于2%(分别测量,取最大值)负载调整率小于等于2%(分别测量,取最大值)效率大于等于70%线性变换情况下,电源输出电压要求:5VDC/1A 波纹小于等于25MVPP(0.5%)3.3VDC/0.5A 波纹小于等于16.5MVPP(0.5%)2~9VDC/0.3A波纹小于等于45MVPP(0.5%)电压调整率小于等于5%负载调整率小于等于5%效率大于等于30%请高手帮我设计下。

MC34063A development aidThis is a simple-minded design tool that allows you to calculate component values MC34063A simple switcher chip. It displays the appropriate scematic diagram (step-up, step-down, or inverting) and checks for current and voltage limits. Feedback resistors are chosen from standard component values so that the output is as close to desired value as possible.I created it as experiment to learn about client-side JavaScript programming and about how it interacts with input forms. Hopefully it proves useful for somebody. Typical input capacitor value is about 100uH, all electorlytics need to be low ESR types. The fast schottky diode should be sufficent for a current needed, 1N5818, 1N5819, 1N5820 and alike will do just fine. 给你一个网页看看有用不 把需要的参数添加进去就可以 你的大部分参数可以找到 www.nomad.ee/micros/mc34063a/index.shtml
