about LTM4633 and LTM4602

Hello,

Regarding to question 2) About LTM4620

LTM4620 is internally compensated. The external 2x0.1uF would affect the stability of the control loop. Please remove them.

If high frequency attenuation need, pF level capacitor can be connected to this COMP pin.

Also components connecting to CLK pin can be removed.

DC1780A-A is the demo board example on using LTM4620 in multiphase.

LTpowerCAD can be used to check the controller stability for the design if needed.

Thank you.

Thanks, I will try to remove 2x0.1uF and components connecting to CLK pin of the LTM4620 circuits.

What about the LTM4633? Whatever I do, the LTM4633's 3 channel outputs are not correct simultaneously. 

Hi，

    I have solved the problem of LTM4633, but LTM4620 is still working abnormal.

    I found that the load capacity make big influence. How much capacity load would be appropriate?
