750 mA buck in a 1.47 mm body
The TPS62840YBGR is a step-down buck converter from Texas Instruments, delivering 750 mA continuous output from an input range of 1.8V to 6.5V. The adjustable output version covers 1.8V to 3.3V, making it a direct fit for 3.3V or 1.8V rails in battery-powered or single-supply systems. Switching at 1.8 MHz, the converter uses synchronous rectification to keep efficiency high across the load range. The 6-pin DSBGA package (0.97x1.47 mm) is the smallest footprint for a 750 mA buck — layout density is the trade-off against a larger QFN.
Temperature grade and package reality
The 6-DSBGA package has no exposed thermal pad — all heat dissipates through the solder balls and PCB copper. A 2-layer board with solid ground plane under the package is sufficient for 750 mA at 125°C ambient. Lifecycle status is Active, and the part is ROHS3 compliant.
The base product number TPS62840 covers multiple output voltage options — confirm the exact suffix for your rail.
