TPS22976: TPS22966 Compatibility

Part Number: TPS22976
Other Parts Discussed in Thread: TPS22966,


Good day.

Our customer is currently using the TPS22966 in their product and they want to switch to TPS22976.

They want to know if this is fully compliant. Pin-to-pin, functionality, etc?

Looking forward to your inputs. Thank you.



  • Hi Cedrick,

    TPS22976 is a pin to pin replacement of TPS22966. It has full compatibility (in terms of operation and control) and also includes thermal shutdown. 

    Please note that some components like the CT capacitance will have to change as the timing specs between TPS22976 and TPS22966 are not the same. The differences between the devices are limited to electrical characteristics like timing, Iq and on resistance.
