The Texas Instruments TPS6281120QWRWYRQ1 is an automotive-grade step-down (buck) converter designed for efficient power management. It supports an input voltage range from 2.75V to 6V and can deliver up to 1A of output current.
This device features an adjustable output voltage, selectable from 0.6V to 5.5V, with an accuracy of ±1% under PWM operation. The switching frequency can be adjusted between 1.8MHz and 4MHz, allowing for optimization of performance and component size. Its typical quiescent current is a low 15µA, contributing to power efficiency in light-load conditions.
The TPS6281120QWRWYRQ1 is housed in a 9-VQFN-HR (3x2 mm) package with wettable flanks, suitable for surface mounting. The operating temperature range is -40°C to 125°C (TA), making it robust for automotive applications. Key features include synchronous rectification for improved efficiency, forced PWM mode, and spread spectrum control for reduced EMI.
This converter is AEC-Q100 qualified, indicating its suitability for demanding automotive environments. It is also functional safety-capable, with documentation available to aid in functional safety system design.
