lm5022的集成双电感msd1278替换成2颗独立电感,对电路的影响?

Other Parts Discussed in Thread: LM5022

请教各位ti工程师,

          之前我有使用过lm5022的电路,9-15v输入,12.5v3.5a输出,里面使用到了一颗互感电感器,

但遇到个问题就是将此输出的电源直接给具备pwm调速的电机供电,电感会发出叫声,

我替换成2颗独立的4.7uH电感就可以避免,当然我还没实际布局在电路里,只是飞线出来焊接的2颗独立电感,

           想请教各位集成的互感电感替换为独立的2颗电感,对实际电路是否造成影响?

比如电压平稳,以及电流供应是否会有落差,非常感谢,等待回复。
