TPS63070EVM-693
This user’s guide describes the characteristics, operation, and use of the TPS63070EVM evaluation
module (EVM). The TPS63070EVM-693 is designed to help the users easily evaluate and test the
operation and functionality of the TPS63070 Buck-Boost Converter. The TPS63070EVM-693 uses the
TPS63070 adjustable version, the output voltage is set to 3.3V/5.0V.The user can select the output
voltage with the VSEL pin. The EVM operates from 2.0V to 16V input voltage. Output currents can go up
to 2A in buck mode and boost mode. This document includes setup instructions for the hardware, a
schematic diagram, a bill of materials (BOM), and printed-circuit board (PCB) layout drawings for the
evaluation module. Throughout this document, the abbreviations EVM, TPS63070EVM-693, and the term
evaluation module are synonymous with the TPS63070, unless otherwise noted.

1 Introduction
The Texas Instruments TPS63070 is a highly efficient, single-inductor, internally compensated, buck-boost
converter in a 15-pin, 2.5-mm × 3-mm HotRod package. Both fixed and adjustable output voltage units are
available.
1.1 Background
The TPS63070EVM-693 uses the TPS63070 adjustable-output voltage version of the integrated circuit
(IC) and is set to a 3.3V / 5.0V output. The fixed-output version(s) can be evaluated on this EVM with
minor modification as stated in section titled,
Fixed Output Operation . The EVM operates with an input
voltage between 2.0 V and 16 V.
