Texas Instruments TPS629210/TPS629210-Q1 Low IQ 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.
Texas Instruments’ automatic efficiency enhancement (AEE) mode holds a high conversion efficiency through the whole operation range without the need to use 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 choose between different external and internal feedback dividers and enable and disable the output voltage discharge capability. In the internal feedback configuration, a resistor between the FB/VSET pin and GND can select between 18 different output voltage options. The TPS629210-Q1 devices are AEC-Q100 qualified for automotive applications. The TPS629210E devices have gold bond wires, a temperature range of –55 to +105°C, and include an SnPb lead finish.
