EVM User's Guide: TPS631012/3
TPS631012/3 Evaluation Module
Description
The TPS631012/3 is a highly efficientcy, single-
inductor, internally compensated buck-boost converter
in a 8-pin, 0.9-mm × 1.8-mm DSBGA package.
The output voltage is programmable from 1.0V to
5.5V in 25mV steps via I2C. The EVM is based
on TPS631012, in which the power-up value of
the ENABLE bit is 0. The only difference between
TPS631012 and TPS631013 is the ENABLE bit.

This user’s guide describes the operation and use of the TPS631012/3EVM. The EVM is designed to help users easily evaluate and test the operation and functionality of the TPS631012/3 buck-boost converter family. The EVM has the output voltage set to 3.3 V . The output voltage can be programmed via I C interface between 1.0... - Page 3 Hardware 2 Hardware 2.1 Background The TPS631012/3EVM uses the TPS631012/3 integrated circuit (IC) , and is set to 3.3 V output voltage. The EVM operates with an input voltage between 1.6 V and 5.5 V. 2.2 Setup This section describes how to properly use the TPS631012/3EVM.
- Page 4 2.5.1 IC U1 Operation This EVM requires an appropriate I C interface, such as the TI USB2ANY, to reconfigure the TPS631012/3. The output voltage can be chosen between two I C-programmable values by using an on-board jumper. See Section for the available output voltage values.
