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. The EVM with the adjust-
able output voltage version is adjusted to 3.3-V output voltage.
The maximum output current at an input voltage down to 0.8 V (single battery-
cell supply) is 100 mA. If two battery cells are used as supply, output currents
up to 200 mA can be drawn at an input voltage down to 1.6 V. The device can
be started into a full load with supply voltages down to 0.9 V over the full tem-
perature range.
The high power conversion efficiency of up to 90%, a low quiescent current of
less than 50
µ
A, and a special power-save mode makes this family of devices
well-suited for battery-powered applications. These EVMs should help to eval-
uate the device directly in the application.
The board can be used, for example, to measure the efficiency of different ex-
ternal components and determine the best for the application. The ripple of the
output voltage be can easily measured, depending on the output capacitor
used. The board is assembled with a 22-
µ
F multilayer ceramic output capaci-
tor from Taiyo Yuden, which has an ultralow ESR to keep the output ripple as
low as possible.
If another fixed-voltage version is of interest, the assembled device can be re-
placed with the desired device. Other fixed voltage versions are TPS61001,
TPS61004, and TPS61005 with 1.5-V, 2.8-V and 3-V output voltage. Free
