MC34845 current capability

Hi,

    I am looking at the MC34845 datasheet and I was wondering why it can only handle total of 180mA (30mA per channel) when it has a 2.1A Boost switch?

 

    His brother MC34844 has a 2.5A boost switch and it is able to manipulate 80mA per channel. It is true that MC34845 can only manipulate backlight of 180mA?

 

    Thanks, Hernán.
