UCC28781: Comparing with UCC28782

Hello Dice-K,

UCC28782 is a ACF controller whom can achieve both of ZVS turn on and leakage recycle , while UCC28781 is a ZVS Flyback controller whom can only achieve ZVS turn on , the leakage energy still dissipated by clamping circuits. UCC28781is attracted by people whom want a better performance than QR flyback while don't  want to pay too much cost like ACF. In a word , from performance perspective , ACF > ZVSF > QR , from cost side , ACF > ZVSF > QR.

Thanks.
