The LTC7124 can be thought of as a spread spectrum lower EMI, lower quiescent current, higher output current, slightly lower maximum input voltage version of the dual 3A LTC3633/A family. An additional feature of the LTC7124 is the ability to parallel 2 outputs for 2-phase, single output 7A operation. The dual 1A LTC3622 is also in the family; it is a micropower device with similar voltage range but does not have spread spectrum capability.
