This user’s guide describes the characteristics, operation, and use of the TPS8269xEVM-207 evaluation
module (EVM). The TPS8269xEVM-207 is a fully assembled and tested platform for evaluating the
performance of the TPS8269xSIP high-frequency, synchronous, step-down DC-DC converters optimized
for battery-powered portable applications. This document includes schematic diagrams, a printed circuit
board (PCB) layout, bill of materials, and test data. Throughout this document, the abbreviations EVM and
TPS8269xEVM and the term evaluation module are synonymous with the TPS8269xEVM-207 unless
otherwise noted.
0.1 Introduction
The TPS8269xSIP device family is a high-frequency, synchronous, step-down DC-DC converters
optimized for battery-powered portable applications. Intended for low-power applications, the
TPS8269xSIP supports up to 500mA or 800mA and all TPS8269xSIP devices allow the use of low-cost
chip inductors and capacitors. With a wide input voltage range of 2.3 V to 4.8 V, the devices support
applications powered by lithium-ion (Li-Ion) batteries with extended voltage ranges. Different fixed voltage
output versions of the TPS8269xSIP are available. These converters operate at a regulated 3-MHz
switching frequency and enter a power-save mode operation under light load currents in order to maintain
high efficiency over the entire load current range. A pulse frequency modulation (PFM) mode extends the
battery life by reducing the quiescent current to 23 μA (typ) during light load operation.
0.1.1 Features
