Product details

The TPS63805YFFT: No last-time-buy window remains; the part is no longer orderable through authorized distribution.

2 A buck-boost in a 15-DSBGA

The switching frequency spreads across 1.4 MHz to 2.7 MHz, and the integrated synchronous rectifier keeps the external component count low — just the inductor, input/output caps, and feedback resistors.

Industrial temperature grade, wafer-level package

The 15-DSBGA package requires a controlled SMT profile and underfill for mechanical reliability in high-vibration environments.

Frequently asked questions

Is TPS63805YFFT obsolete?

The last-time-buy window has closed. It is not recommended for new designs.

What is the replacement for TPS63805YFFT?

No official successor is listed by Texas Instruments. The TPS63806YFFT is a sibling in the same family — verify the output voltage and current ratings against your BOM before substituting. For new designs, consider TI's current buck-boost parts such as the TPS63802 or TPS63810.
