TPS55340-Q1: Switching losses estimation

Part Number: TPS55340-Q1
Other Parts Discussed in Thread: TPS55340

Hi,

TPS55340 is used in SEPIC configuration and I need to estimate IC temperature.

Rds_on is presented in datasheet, so it's possible to calculate power dissipation when internal MOSFET is is open.

But how can I calculate switching losses? I can't find in datasheet nothing useful for this pupouse. Am I missing something?
