LM5116: 负电压的正确设计评估及推荐相关的DCDC模块

Part Number: LM5116
Other Parts Discussed in Thread: TPS54560, TPS5430, TPS54160, LM1086, TPS7A33

尊敬的TI工程师,您好:

       ①我想选型一款DCDC模块,输入为+24V左右,需要输出一个-18V@2A的低纹波输出,在负电压输出的器件选型上我在webench上看到了一款比较合适的型号LM5116MH/NOPB,推荐的设计原理图如图,如果照此严格设计是否可行或者有其它推荐的简单设计能满足性能的正电压输入负电压输出型DCDC,谢谢!

 

        ②或者推荐一款能够输入+24V左右,能同时输出-18V@2A和+18V@2A的双路输出模块,谢谢!
