AM437x功耗问题

Other Parts Discussed in Thread: TPS65218

你好, 我想咨询一下AM437X上的功耗问题。

参考processors.wiki.ti.com/.../AM437x_Power_Consumption_Summary,上面说的deepsleep模式下,芯片的功耗在5mw左右。那AM437X DDR(单个) SD卡 PMIC(tps65218)的情况下,不加任何外设,功耗会达到多少呢,核心板上基本上是参考 am437x_gp_evm的,我们现在测到的是85mW,这个值是不是有点过高了,我们想尽可能的降低休眠功耗,请问该如何着手。

望不吝赐教,谢谢!!!
