HI Sir:

I switched from TPS54560 to TPS54560B as suggested by the TI dealer. And I want to know what process was upgraded from TPS54560B and what are the differences between the parameters and TPS54560.

    Hello ,

    The TPS54340/360/540/560B from Texas Instruments is a pin to pin drop in upgrade to the existing TPS54340/360/540/560 buck converter family. The TPS54340/360/540/560B is available in an 8-terminal thermally enhanced HSOIC PowerPAD™ package like the current generation TPS54340/360/540/560. As TI continues to innovate and improve its manufacturability and processes, the TPS54340/360/540/560B offers higher reliability and performance. Hence, we recommend TPS54340/360/540/560B for new designs for our customers in the industrial, automotive and communications markets and update the status of TPS54340/360/540/560 to NRND (Not Recommended for New Designs). The status of TPS54340/360/540/560 will not be changed to EOL (End Of Life).

    Here are the imporivements :

    •Addition of Poly-Imide (PI) coat on IC’s top layer

    •Increased reliability: Improved output OVP circuit .

    •Increased current limit: 7.5A to 7.9A (typical), 8.8A to 9.5A (maximum).
