LMX2594EVM: Reducing power consumption

Other Parts Discussed in Thread: LMX2594

Hi, I am trying to reduce the power consumption of the LMX2594. I have already configured the OUTA_PWR and OUTB_PWR registers to be equal to 0 (the resulting current consumption is 0.33A), are there any other registers (or any other settings) I can configure to reduce this current consumption even further? Thank you.

HI JL,

What is your target current consumption?

Hi Noel,

I don't have a specific target number, but ideally as little current as possible.

Hi JL,

Reducing reference clock / fpd frequency and charge pump current can reduce the overall current consumption a bit. The core current consumption is around 300mA, so there is not much room you can improve.
