请教高手:buck-boost方案,VIN＝DC 10~30,Vout＝DC12V,Imax＝500ma如果不加扩流可以做到吗?

34063要擴流管,400MA就不要了.
请问是这样的接法吗?扩流的方法对吗?谢谢

请教大侠,你说的电流可达到1A的升降压电路是不是这样的?请指教电路是否正确,可否达到升降压效果或说明原理?

34063的2腳要加管的.你這個圖就不和上面那個不一樣了,電路不能升壓了.L1和D2間接到另一個MOS的D,2腳接MOS的G.在GS加2.2K電阻.
我不是很明白,这个是我更改的图你看是不是这样的

MOS是用N溝的.2.2K電阻接在34063的2和地之間.按工作原理分析嗎!兩管ON時給電感蓄能.OFF時由電感放電.
大侠,我测试了下面这个电路,电流可以达到我的要求,短路时可达到1.5A,升压时还行,但是如果是降压的话效率就很低,只能达到50%,请问如何提高效率,如何更改,谢谢!
