MPM54304-0003 configuration

hi,
In MPM54304-0003 this suffix mode, its configuration as table 9 and table 10. It needs external resistor divider to set the output voltage for channel 1, channel 2 and Channel 3/4, right?

I am confused that in this reference design. The chip is MPM54304-0001. Suffix 0001 also configure this chip to work in external resistor divider mode. Yet, the reference design does not have external resistors.

So, my question is: Are external resistor divider needed for set voltages for out1, out2 and out3/4 when using MPM54304-0003?

Thank you.

Hello,

Yes, for 0003 suffix it uses external resistive divider to set the output voltage. Does it look like a block diagram showing the power on each rail? If so, it is to simplify the diagram and just show what is being outputted.

I don’t remember what it is exactly. The webpage was removed. But I am clear about 003 suffix now. Thank you.
