TPS629210/TPS629210-Q1 Low IQ Buck Converter

Texas Instruments TPS629210/TPS629210-Q1 Low I_Q Buck Converter is a highly efficient, small, and highly flexible synchronous step-down DC-DC converter that is easy to use. A wide 3V to 17V input voltage range supports various systems powered from either 12V, 5V, or 3.3V supply rails or single-cell or multi-cell Li-Ion batteries. The TPS629210/TPS629210-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 small loads.
