Hello,
I'm designing two SMPS with the Linear Technologies' LTPowerCAD tool,set; by the way a very interesting platform.
Due to specific constraints I will not be able to use a single SMPS with multiple output derivations.
However, unlike the Texas platform I used earlier, this one doesn't provide an option to use the same CLK from one chip to another; I mean, despite marked the option for that, in the diagram generated for simulation in LTSpice it is not clear how to do this; in fact, even the controller datasheet doesn't makes it clear how to do this. I'm using the LTC3891 as a 5v converter for the control logic and the LTC3777 for the Power.
Does anyone have any information or a link on how to proceed with this oscillator clock sharing?
