I'm a DFAE in Japan. Our customer give us a question about the dead time of LTC7060. Could you please tell me the formula to calculate RDT when he wants to set a dead time of over 76ns.
The EC table for the LTC7060 provides RDT values for dead-times of 43nsec, 62nsec, 76nsec and 250nsec (RDT open) in the EC table. Also, as you are aware, page 10 provides a formula for dead-times of 76nsec and less. However, we do not have a formula for dead-times between 76nsec and 250nsec. If you need further help then contact me directly @ email@example.com.
Per the designer the formula in the data sheet can be used to calculate the RDT for dead-times up to 200nsec. Beyond that, the dead-time vs RDT curve flattens as the dead-time reaches the maximum of 250nsec. The dead-time of the LTspice model also follows the formula for dead-times up to 200nsec.
