Texas Instruments TPS629206/TPS629206-Q1 Low IQ Buck Converters are highly efficient, small, and highly flexible synchronous step-down DC-DC converters that are easy to use. A wide 3V to 17V input voltage range supports various systems powered from either 12V, 5V, or 3.3V supply rails, single-cell or multi-cell Li-Ion batteries. The TPS629206/TPS629206-Q1 can be configured to run at either 2.5MHz or 1MHz 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 4µA typical quiescent current provides high efficiency down to the smallest loads.
