UCC24612: UCC24612-1 for LLC

Section 7.3.2 (page 14) of the UCC24612 datasheet has the following explanation

"In UCC24612, two different versions are available.  UCC24612-1 has an inherently short turn-on propagation delay (80 ns typical) and can be used with the converters that need shorter delay, such as standard Flyback converters or Active Clamp Flyback converters using GaN MOSFETs as main switches. UCC24612-2 has a longer 170-ns turn-on delay, to further ignore the leading edge spike and can be used with Active Clamp Flyback using Si-based super-junction MOSFETs as the main switch or LLC converters.  Due to the longer turn-on delay, UCC24612-2 also increases its minimum on time-to 540ns to allow further enhancement on dealing with resonant-shape current, which makes a better choice for Si-based super-junction MOSFETs as the main switch or LLC converters."
