TLC6C598: Power dissipation

Part Number: TLC6C598

Hello,

How can I calculate the power dissipation of the LED driver TLC6C598QPWQ, Attached the schematic for reference the current through each channel is set to 11mA.

I got one formula like [PD= VCC x ICC (Vout x Iout) x number of channel,] but in below case shall I consider the Vf of each LED as VOUT. 

Regards,
