Other Parts Discussed in Thread: LM2576, TPS54140, DAC082S085, OPA547
如题,5V输入,正负5V输出,输出电流在300mA~700mA,各位大神可否帮忙提供一下方案供参考。
附件的参考设计是否可以用在LM2576-5上,实现+5V 到-5V的转换?谢谢!

Hi
可以的。 参照下图正转负的电路,你给的电路是负转负的,将芯片换成LM2576.
其次你的电流比较小,或者可以用TPS54140这类芯片:http://www.ti.com.cn/cn/lit/an/slva317b/slva317b.pdf 芯片用TPS54140. 等等
