最近在做运放的电源,使用了SLVA369A(www.ti.com/.../slva369a.pdf)中的电路,但是在耦合电感和肖特基二极管时不知道该怎么选,希望能给推荐一个。谢谢!

Hi
这个文档:http://www.ti.com/lit/an/slva369a/slva369a.pdf 上写得比较详细,可以用MSD1278, MSD7243, LPD3015, and LPD4012.
其中例如Coilcraft的MSD1278系列 :http://www.coilcraft.com/msd1278.cfm 选择150uH的 MSD1278-154
肖特基选型要看你的输入电压: The diode voltage needs to be greater than the difference of the maximum input voltage and output
voltage. 电流计算见这个文档的第五页。
