4 MHz switching — inductor shrinks, layout tightens
The TPS62802YKAT is a 1 A synchronous step-down buck converter from Texas Instruments, switching at 4 MHz.
Input range and output voltage flexibility
The output is adjustable from 1.8 V up to 3.3 V, with a fixed 1.8 V option available. This range suits point-of-load regulation for MCUs, RF transceivers, and sensor interfaces where the load stays under 1 A.
Temperature grade and package realities
The 6-DSBGA package (1.05 mm x 0.70 mm) saves board area but demands a controlled reflow profile — the 0.4 mm pitch bumps require precise solder paste deposition and X-ray inspection for voiding. No underfill is specified for standard use, but mechanical shock or repeated thermal cycling in a high-vibration assembly may warrant evaluation.
