TPS40057 dead time

Hamamoto,

Thank you for your interest in TI parts. There is no specific dead-time specification.  The dead-time is determined by the propagation delay of a comparator (HDRV – SW or LDRV – PGND) through to the opposite driver.  It is typically 100ns and varies approximately 30%.  This does not include the rise or fall time of the respective gate drive signals due to the gate drive resistance and gate-to-source capacitance of the FETs.

Hi MC

Thank you.
