3 Description
The automotive-qualified TPS629211-Q1 device is a
highly efficient, small, and highly flexible synchronous
step-down DC-DC converter that is easy to use. A
wide 3-V to 10-V input voltage range supports a wide
variety of systems powered from either 9-V, 5-V, or
3.3-V supply rails, or single-cell or multi-cell Li-Ion
batteries. The TPS629211-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).
