请问各位有什么好的方案可以实现以下要求?
1, 输入电压: 8~36V DC
2, 输出电压:16VDC/2.5A 5VDC/10A
3, 输入输出隔离
车载隔离电源设计

现在国办有推出一个buck-boost芯片,有没有谁用过啊?效率怎么样?国办的东西,我一直担心它的效率.现在国办有个LM5116的效率不错,我有用过,同步整流的,我做到了6安培,效率最低88,最高有95.
Hi, 88% for 4:1 input range is pretty good, does it isolation?
You can refer thr Synqor's module(9-36 input)12V/100W output, 90%(isolated) and others-I will give you next-time, if you need?
Thanks

对不起,我没有说清楚,LM5116是单纯的BUCK,非隔离的.我需要你说的这方面的资料,请帮忙发到以下邮箱:szchengsz@163.com谢谢.
Why isolation? Car-used power moduels are all grounded via the CAR-body! You can try a isolated D/D + a 5V buck, the only dis-asvantage is less efficiency! You look not like a power-electronic Major? Do you get the reference data?

现在使用隔离电源,是因为非隔离电源的地线回路(因为地线搭铁)会带来很多干扰,使用隔离电源就是将设备这边的回路与汽车电源系统隔离开来,当然这种运用主要用于比较破旧的汽车(或者说跟我们主设备的方案有关).
哦,我把邮箱地址输错了:smchengsz@163.com,麻烦你再发一遍好吗?

I am not sure that is potted or not? most of this are open frame module. You can try LM 5025, they says it's good. http://bbs.dianyuan.com/topic/214791
