LM5146: LM5146 in 2 ph interleaving

Part Number: LM5146
Other Parts Discussed in Thread: LM5143, LM5149-Q1, LM5148-Q1, LM5149-Q1EVM-400

Hi Timothy,

In addition to relative thread, can you explain a bit about why LM5146's voltage mode control is inappropriate for 2-ph interleaving operation? LM5143's current control maybe engages in current sharing?

Customer wants to use LM5146 in parallel for 48V (36~62V) input to 12V output. LM5143 supports only upto 65Vin. They should go for LM5146.
