LTC7130 Qt and Qb not specified in datasheet

the LTC7130 datasheet (LTC7130fb.pdf) has a chapter "efficiency considerations". In this chapter (page 27) some remarks about switching losses are made, including the formula Igatechg = f(Qt+Qb), where Qt and Qb are the gate charges of the internal top and bottom power switches. However, these values are not specified in the datasheet. Is this information available?
