The 3 MHz switching frequency lets the designer use a small inductor — typically 1 µH or less — keeping the total solution footprint compact. ## 3 MHz switching enables small passives At 3 MHz, the inductor value and output capacitor can be significantly smaller than what a 1 MHz or 500 kHz regulator would require. For a 500 mA rail, a 1 µH inductor and a 10 µF ceramic output cap are typical — both in 0603 or 0805 case sizes. The trade-off is slightly higher switching losses, but at 500 mA the efficiency is still competitive for a local point-of-load rail. The input voltage range from 2.05 V minimum to 6 V maximum covers single-cell Li-ion (3.0 V to 4.2 V) and regulated 3.3 V or 5 V buses. The 2.05 V minimum is low enough to run from a near-depleted Li-ion cell, which is useful in battery-powered portable equipment. ## Industrial temperature grade and active lifecycle The part is supplied in Tape & Reel (TR) or Cut Tape (CT) packaging, both in the 6-UFDFN package that reflows as 6-SON (1.45×1 mm). ## Sourcing and BOM-fit note It is a single-source part from Texas Instruments — no direct second-source exists with the same pinout and package. Confirm the mating inductor and capacitor values against the datasheet application circuit before committing the layout.","metaTitle":"TPS62239DRYT – Texas Instruments 500 mA Step-Down Buck","metaDescription":"TPS62239DRYT from TI: 500 mA fixed 1 V output, 3 MHz buck converter in 6-SON (1.45×1 mm).
