TPS43060/61 for SEPIC design

Matthew Yenn

Other Parts Discussed in Thread: TPS43060, TPS43000

Since its not noted specifically on the TPS43060/61 datasheet... Does anyone know if there are issues using the TSP43060 for a SEPIC design? I have used the TPS43000 before but I need a higher input voltage than it can handle.

Thanks

It won't be possible to use TPS43060 in synchronous SEPIC design because we won't be able to provide the required gate drive for the sync FET.

It is possible to use these parts as a synchronous SEPIC with the circuit below at the gate of the synchronous rectifier to AC couple the HDRV signal. See the areas boxed in red.
