600 kHz switching — inductor sizing and efficiency
Switching at 600 kHz, the TPS62101D sits in the middle of the frequency range for buck converters in this current class. That frequency lets you use a physically small inductor — typically in the 10 µH to 22 µH range — without pushing switching losses high enough to need a heatsink.
The tube shipping medium keeps the parts aligned and ESD-safe on the shelf — no moisture-sensitive reel bake required before assembly.
For the storeroom, this means one less part to worry about for the next several years — stock what you need and rotate normally.
