DESCRIPTION
The
TPS61040/41
converter dedicated for small to medium LCD bias
supply and white LED backlight supplies. The device
is ideal to generate output voltages up to 28 V from a
dual cell NiMH/NiCd or a single cell Li-Ion battery.
The part can also be used to generate standard
3.3-V/5-V to 12-V power conversions.
APPLICATIONS
LCD Bias Supply
White-LED Supply for LCD Backlights
Digital Still Camera
PDAs, Organizers, and Handheld PCs
Cellular Phones
Internet Audio Player
Standard 3.3-V/5-V to 12-V Conversion

LOW-POWER DC/DC BOOST CONVERTER IN SOT-23 AND SON PACKAGES
is
a
high-frequency
boost
The
frequency up to 1 MHz. This allows the use of small
external components using ceramic as well as
tantalum output capacitors. Together with the thin
SON package, the TPS61040/41 gives a very small
overall solution size. The TPS61040 has an internal
400 mA switch current limit, while the TPS61041 has
a 250-mA switch current limit, offering lower output
voltage ripple and allows the use of a smaller form
factor inductor for lower power applications. The low
quiescent current (typically 28
μ
A) together with an
optimized control scheme, allows device operation at
very high efficiencies over the entire load current
range.
