LTM4613 parallel operation connections

Category: Datasheet/Specs
Product Number: LTM4613

Hello,

Can you provide a listing of the connections that are required to operate in parallel?

I see in the datasheet a reference to figure 21 but there is no explicit listing of the connections required. I am uncertain which of the connections in Figure 21 are required for parallel operation and which are choices made in the example schematic that may not apply to my design.

  • Vfb seems required
  • Vout obviously required
  • MARG0/1 seem required if used, but if unused don't care?
  • FCB i think needs to be matched
  • PLLIN unused is don't care?
  • MPGM must not be shared per datasheet notes
  • Fset, if used, must be connected? Must have matching resistors but not connected?
  • Comp pins are connected but unclear if this is required?
  • Pgood I'd guess can be shared or not
  • Run must be connected?
  • Track/SS must be connected? I assume current sources add and I must adjust SS time by factor of N?
  • Layout considerations? Should each regulator be treated ~ independently for current loops and each match Figure 17 as best as possible?

Thanks.

Mark
