DCDC電源變換器的設計和制作

開關變換情況下，電源輸出電壓要求28VDC/0.15A 紋波小于等于0.28Vpp5vdc/0.6A 紋波小于等于0.5Vpp電壓調(diào)整率小于等于2%（分別測量，取最大值）負載調(diào)整率小于等于2%（分別測量，取最大值）效率大于等于70%線性變換情況下，電源輸出電壓要求：5VDC/1A 波紋小于等于25MVPP（0.5%）3.3VDC/0.5A 波紋小于等于16.5MVPP（0.5%）2~9VDC/0.3A波紋小于等于45MVPP（0.5%）電壓調(diào)整率小于等于5%負載調(diào)整率小于等于5%效率大于等于30%請高手幫我設計下。

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. 給你一個網(wǎng)頁看看有用不 把需要的參數(shù)添加進去就可以 你的大部分參數(shù)可以找到 www.nomad.ee/micros/mc34063a/index.shtml
