Please help me chose one chip about DCDC



Good afternoon~all,I’m so happy when I found this forum cause I think maybe someone here is able to solve my troubles.Anyway,thank you for reading my post firstly.

I’m an electronic enthusiast and my professional knowledge is limited. I didn’t find chip for a long time so that I don’t know what kind of chip of power converts are common. So hoping that someone here can help me.My sutiations are following:

DC IN: 8v-24v, 52-60mA

DC out: 3.3v

Requires:

1).The efficiency should be over 60%.

2).The chip is easy to find,and the Compatible chip should be more.

3).The peripheral device should less than 6.

I have found one--LM2596 ( this one )from internet,but I don’t know if it’s the most suitable one ,please help me have a look ! Or could you recommend one to me?

Thanks a lot!
