The automotive-qualified TPS6292xx-Q1 family of
devices are highly efficient, small, and highly flexible
synchronous step-down DC-DC converters that are
easy to use. A wide 3-V to 17-V input voltage range
supports a wide variety of systems powered from
either 12-V, 5-V, or 3.3-V supply rails, or single-cell
or multi-cell Li-Ion batteries. The TPS629210-Q1 can
be configured to run at either 2.5 MHz or 1 MHz
in a forced PWM mode or a variable frequency
(auto PFM) mode. In auto PFM mode, the device
automatically transitions to power save mode at
light loads to maintain high efficiency. The low 4-µA
typical quiescent current also provides high efficiency
down to the smallest loads. TI's automatic efficiency
enhancement (AEE) mode holds a high conversion
efficiency through the whole operation range without
the need of using different inductors by automatically
adjusting the switching frequency based on input and
output voltages. In addition to selecting the switching
frequency behavior, the MODE/S-CONF input pin can
also be used to select between different combinations
of external and internal feedback dividers and
enabling and disabling the output voltage discharge
capability. In the internal feedback configuration, a
resistor between the FB/VSET pin and GND can be
used to select between 18 different output voltage
options (see Table 8-2).
