Other Parts Discussed in Thread: TPS65265, TPS43060, TPS55330

Hi Support,

Am designing a power supply unit for communication device using TI’s buck converter of TPS65265 and post regulation using boost converter of TPS43060 and TPS55330.
It is possible to synchronize clock of buck converter (master) and boost converter (slave)?
If not, what is the most suitable external clock to be used for sync freq at 610kHz?

Thanks.

Moving your post to non-isolated DCDC for better support.

All three of those devices allow for external synchronization, however none have a clock output. If it were me, I would probably synchronize all of them to an external clock. I would individually buffer each clock input.
