Synchronous buck at 750 mA — what the 1.8 MHz switch means for your rail
The TPS62841DLCR is a synchronous step-down (buck) converter from Texas Instruments that delivers up to 750 mA continuous output from a 1.8 V to 6.5 V input rail. The 1.8 MHz switching frequency lets you use small-value inductors and ceramic output capacitors — typically a 1 µH to 2.2 µH inductor and 10 µF to 22 µF output cap — which keeps the total solution footprint tight on a 2-layer board. The efficiency holds up across light loads, which matters for always-on or battery-backed rails.
Temperature grade and package — where this regulator survives
The 8-VSON-HR package (2 mm x 1.5 mm) with an exposed thermal pad needs a solid copper pour on the top layer to pull heat out of the die. Surface-mount only — the 0.50 mm pitch VSON lands on a standard 8-pin footprint with a centre pad.
