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

μ

A) together with an optimized control scheme,

allows device operation at very high efficiencies over
the entire load current range.
