Page 7: Introduction
Chapter 1 Introduction The Texas Instruments TPS6100x are low-power single-cell boost converters. The TPS61002, TPS61003, and TPS61006 are fixed voltage versions with 1.8-V, 2.5-V and 3.3-V output voltage. The TPS61000 can be adjusted with an external voltage divider to an output voltage between 1.5 V and 3.3 V. Each of these four versions is supported with its own EVM. -

Layout Considerations 3.3 Layout Considerations The basic components of a boost converter topology (as shown in Figure 3–1) are placed on the top side of the EVM. These are the components which carry the high currents. The ground plane is divided into two parts that are connected to the ground pin of the device. -

Page 17: Low-Battery Function Lbi And Lbo
Low-Battery Function LBI and LBO 4.2 Low-Battery Function LBI and LBO The low battery feature is typically used to supervise the battery voltage and to indicate when the voltage goes below an adjustable threshold voltage. The threshold voltage can be adjusted by an external resistive divider connected to the low-battery input (LBI) as shown in Figure 4–2.
