Spec.

Achieve greater compactness and thinness
Enabled interleaving of 2 or more phases. Multiphasing allows for devices to be made smaller for each phase, to achieve greater compactness and thinness.
Allowing for detection loss to be reduced
A multiplier method makes detection of required input lines unnecessary, allowing for detection loss to be reduced.

Current critical operation can be achieved throughout
Two pieces of data, the ON timing and ON width, are transmitted from the nth phase IC to the nth+1 phase IC.
Current critical operation can be achieved throughout by completely equalizing the ON width of each phase.
Output diode short protection
Can detect output diode short conditions to protect against continued oscillation. Latch stop occurs after detection.
