I am using two LTM4623 DC converters that share the same VIN [5V]. This VIN is coming from an output of another wide input Buck DC converter (1st Stage) that is taking a 36V and transforming it to 5V.
So the LTM4623 share the same VIN=5V rail:
- First LTM4623 converts from VIN=5V to 3.3V
- Second LTM4623 converts from VIN=5V to 1.1V
Can we use some phase relationship (in-phase or out-of-phase) by connecting CLKOUT to CLKIN to reduce the power demand on the VIN power rail?
Any proposal regarding the phase relation between the two converters to reduce the EMI radiations on the board or also to reduce the Vout ripple of each converter?
Adding a Figure to illustrate the question.
