LM5017技术手册关于VCC极限值的描述,两个地方不一致

Other Parts Discussed in Thread: LM5017

LM5017技术手册（SNVS783H–JANUARY2012–REVISE DDECEMBER 2014）中第4页中VCC to RTN极限值为13V，第10页中描述到if the VCC voltage is driven externally by an alternate voltage source between 8.55V and 14V,the internal regulator is disabled.This reduces the power dissipation in the IC. 这里提到范围能到14V，不知道实际应该是多少？另外，我的电路Vout=15V,想通过这个外部给VCC供电，请指点。谢谢！
