DESCRIPTION
The TPS61040/41 is a high-frequency boost con-
verter 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

LOW POWER DC/DC BOOST CONVERTER IN SOT-23 PACKAGE
The TPS61040/41 operates with a switching fre-
quency up to 1 MHz. This allows the use of small
external components using ceramic as well as tanta-
lum output capacitors. Together with the tiny SOT23
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 quiesc-
ent
current
(typically

optimized control scheme, allows device operation at
very high efficiencies over the entire load current
range.
