Doesn't TI have a IC or controller for multiple phase buck, DC to DC except

Johnson Pi

Other Parts Discussed in Thread: TPS53679, TPS53622, TPS53681, TPS53659, TPS53667, TPS53647, LM5119

Does TI have analog IC (not MCU) for multiple phase buck down application some other than TPS53679. I would like to use some simple ICs.

Thanks,

Hi Johnson,

For other multiphase buck regulator controllers you could look at either the TPS53659 or TPS53622 for Intel applications. Otherwise we offer the TPS53647, TPS53667, or TPS53681 for non-Intel power applications.

The TPS53679, TPS53659, TPS53622, and TPS53681 can all be used for either one or two outputs depending on your configuration and current level needs. TPS53647 and TPS53667 both can only do one output for either a max phase count of 4 or 6.

Let me know if you need anything else.

Cheers,

Carmen

Hey Johnson,

Unfortunately we do not have any products in the multiphase group that can handle 400V on the input. In case you had a typo and meant 40V, the LM5119 would be able to fit your application when configured to 2-phase mode.

Thanks,

Carmen
