• Standard 3.3-V or 5-V to 12-V Conversion
3 Description
The TPS6104x is a high-frequency boost 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 or 5-V
to 12-V power conversions.
The TPS6104x operates with a switching frequency
up to 1 MHz. This frequency allows the use of small
external components using ceramic as well as
tantalum output capacitors. Together with the thin
WSON package, the TPS6104x gives a very small
overall solution size. The TPS61040 device has an
internal 400-mA switch current limit, while the
TPS61041 device 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
μA) together with an optimized control scheme,
allows device operation at very high efficiencies over
the entire load current range.
