Part Number: TPS54340B-Q1

Hello TIer,

Could you help us to provide TPS54340B-Q1 minimum off time? Looks webside show Dmax is 98% at what switching frequency condition? 

In our design output voltage design 8VDC and Input range from 9VDC to 16VDC.

  • At high duty cycles this device will hold the top switch on for many switching cycles and periodically
    turn on a small low side switch to recharge the boot cap. The best way to see this is to get an EVM
    and look at the waveforms.
