This

User’s

Guide

describes

the

characteristics,

operation,

and

use

of

the

TPS63000EVM evaluation module (EVM). This EVM is designed to help the user easily
evaluate and test the operation and functionality of the TPS63000. This User’s Guide
includes setup instructions for the hardware, a schematic diagram, a bill of materials
(BOM), and PCB layout drawings for the evaluation module.

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.

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.

Table 1

provides a summary of the TPS63000EVM-148 performance specifications. All specifications are

given for an ambient temperature of 25

°
