DescriptionThe TPS6104x-Q1 devices are high-frequency boost
converters for automotive applications. The devices
are ideal for generating output voltages upto 28V
from a pre-regulated low voltage rail, dual-cell
NiMH/NiCdora single-cell Li-Ion battery, supporting
input voltages from 1.8Vto6V.
The TPS6104x-Q1 devices operate witha switching
frequency upto1 MHz, allowing the useof small
external components such as ceramic as
tantalum output capacitors. Combined with the
saving, 5-pin SOT-23 package, the TPS6104x-Q1
devices accomplisha small overall solution size. The
TPS61040-Q1 device has an internal 400-mA switch
current limit, while the TPS61041-Q1 device hasa
250-mA switch current limit, offering lower output
voltage ripple and allowing the useofa smaller form
factor inductor for lower-power applications.
The TPS6104x-Q1 devices operate ina 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 operationof the devicesat
high efficiencies over the entire load current range.
