TPS61040, TPS61041SLVS413I –OCTOBER 2002–REVISED DECEMBER 2016
TPS6104x Low-Power DC-DC Boost Converterin SOT-23 and WSON Packages Features 1.8-Vto 6-V Input Voltage Range Adjustable Output Voltage Rangeupto28V 400-mA (TPS61040) and 250-mA (TPS61041)
Internal Switch Current Upto 1-MHz Switching Frequency 28-μA Typical No-Load Quiescent Current 1-μA Typical Shutdown Current Internal Soft Start Availablein SOT23-5, TSOT23-5,
and 2-mm× 2-mm× 0.8-mm WSON Packages
Applications LCD Bias Supply White-LED Supply for LCD Backlights Digital Still Camera PDAs, Organizers, and Handheld PCs Cellular Phones Internet Audio Players Standard 3.3-Vor 5-Vto 12-V Conversion
DescriptionThe TPS6104xisa high-frequency boost converter
dedicated for smallto medium LCD bias supply and
white LED backlight supplies. The deviceis idealto
generate output voltages upto 28V froma dual-cell
NiMH/NiCd ora single-cell Li-Ion battery. The part
can also be usedto generate standard 3.3-Vor 5-V 12-V power conversions.
The TPS6104x operates witha switching frequencyto1 MHz. This frequency allows the useof small
external components using ceramic as well as
tantalum output capacitors. Together with the thin
WSON package, the TPS6104x givesa very small
overall solution size. The TPS61040 device has an
internal 400-mA switch current limit, while the
TPS61041 device hasa 250-mA switch current limit,
offering lower output voltage ripple and allows the
useofa smaller form factor inductor for lower power
applications. The low quiescent current (typically 28
μA) together with an optimized control scheme,
allows device operationat very high efficiencies over
the entire load current range.
