Introduction
The Texas Instruments TPS63000 is a high efficient single inductor buck-boost converter in a 10-pin,
3-mm × 3-mm QFN package. Both fixed and adjustable output voltage units are available.
1.1
Background
The TPS63000EVM-148 uses the TPS63000 adjustable version, and is set to 3.3-V output. The EVM
operates with full-rated performance with an input voltage between 3.0 V and 5.5 V.
