FEATURES
DESCRIPTION
1.8-V to 6-V Input Voltage Range
The
TPS61040/41
is
a
high-frequency
boost
converter dedicated for small to medium LCD bias
Adjustable Output Voltage Range up to 28 V
supply and white LED backlight supplies. The device
400-mA (TPS61040) and 250-mA (TPS61041)
is ideal to generate output voltages up to 28 V from a
Internal Switch Current
dual cell NiMH/NiCd or a single cell Li-Ion battery.
Up to 1-MHz Switching Frequency
The part can also be used to generate standard
3.3-V/5-V to 12-V power conversions.
28-mA Typical No-Load Quiescent Current
1-mA Typical Shutdown Current
The
TPS61040/41
operates
with
a
switching
frequency up to 1 MHz. This allows the use of small
Internal Soft Start
external components using ceramic as well as
Available in SOT23-5, TSOT23-5,
tantalum output capacitors. Together with the thin
and 2 × 2 × 0.8-mm SON Packages
SON package, the TPS61040/41 gives a very small
overall solution size. The TPS61040 has an internal
APPLICATIONS
400 mA switch current limit, while the TPS61041 has
LCD Bias Supply
a 250-mA switch current limit, offering lower output
voltage ripple and allows the use of a smaller form
White-LED Supply for LCD Backlights
factor inductor for lower power applications. The low
Digital Still Camera
quiescent current (typically 28 mA) together with an
PDAs, Organizers, and Handheld PCs
optimized control scheme, allows device operation at
Cellular Phones
very high efficiencies over the entire load current
range.
