Description

The TPS6292xx 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 TPS629203 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).
