Hello,

TPS51518 use adaptive dead time scheme. There is anti-cross circuit inside IC to ensure high-side gate and low-side gate will not be turned on at the same time.

Thanks

Hi,

Have you define the minimum dead time of TPS51518? Cause function of dead time is trigger by controller, and will not turn on both H/L side mosfet during this period. I am understand that there is some external component will impact the length of time. Could you please give me a range?

Hello,

As the part uses adaptive dead time scheme, we don't have spec for minimum dead time.

Thanks

Qian
