LTC3779 - multiple in parallel

Category: Hardware
Product Number: LTC3779

Hi,

How can I use LTC3779 to design 20-120V input and 56V output 2kW or 3kW converter? Primary reason to select this IC over LTC7810 is the output current limit function.

1. If the LTC3779 was not designed for multiphase operation OR multiple in parallel configuration then what is the maximum power output and current specs for the LTC3779? 

1b. Can multiple LTC3779 be connected via LTC4370 or similar (as suggested https://www.analog.com/en/resources/technical-articles/novel-current-sharing-ic-balances-two-supplies-with-ease.html ) 

2. If I use LTC7810, what circuit can I add for an output current limit that is high efficiency?
