3 Description
The TPS6104x-Q1 devices are high-frequency boost
converters for automotive applications. The devices
are ideal for generating output voltages up to 28 V
from a pre-regulated low voltage rail, dual-cell
NiMH/NiCd or a single-cell Li-Ion battery, supporting
input voltages from 1.8 V to 6 V.
The TPS6104x-Q1 devices operate with a switching
frequency up to 1 MHz, allowing the use of small
external components such as ceramic as well as
tantalum output capacitors. Combined with the spacesaving,
5-pin SOT-23 package, the TPS6104x-Q1
devices accomplish a small overall solution size. The
TPS61040-Q1 device has an internal 400-mA switch
current limit, while the TPS61041-Q1 device has a
250-mA switch current limit, offering lower output
voltage ripple and allowing the use of a smaller form
factor inductor for lower-power applications.
The TPS6104x-Q1 devices operate in a pulse
frequency modulation (PFM) scheme with constant
peak current control. The combination of low
quiescent current (28 μA typical) and the optimized
control scheme enable operation of the devices at
high efficiencies over the entire load current range.
