BBB means BeagleBone Black
BBB_SCH.pdf shows it can use TPS65217C to implement the design of 1.5V/1.35V for DDR3/DDR3L. but the wiki page shows only TPS65217D can be used for DDR3L, can you confirm this? which one is correct?
below link shows only TPS65217D can be used for DDR3L
你看看 这个 http://www.mouser.com/catalog/specsheets/BBB_SRM.pdf
实际上这里的DDR3L还是工作在1.5V的。
如果你需要1.35v,还是需要选择tps65217D
我看到这个SRM了,但是它确实是提到了 也可以改成1.35V工作(难道他的意思是是换PMIC的料TPS65217D前提下, 毕竟他们的封装完全一样), SRM确实没有提到。
