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
