Product details

Fixed 2.1V rail at 500 mA — 3 MHz switching keeps the inductor small

The TPS62234DRYR is a fixed-output step-down buck regulator from Texas Instruments delivering 500 mA continuous current at a regulated 2.1V output. Input voltage range spans 2.05V to 6V, making it suitable for single-cell Li-ion or 3.3V/5V rails. The integrated synchronous rectifier boosts efficiency at light loads — a practical advantage for battery-powered gear where quiescent current matters.

Temperature grade and package — board-level fit for tight spaces

The 6-SON package measures 1.45x1 mm — a 0.5 mm pitch land pattern that demands careful solder-paste stencil design but rewards with minimal board real estate. The 6-UFDFN package (Supplier Device Package 6-SON) is a leadless, thermally enhanced DFN with an exposed pad.

Active production — sourcing posture and package options

ROHS3 compliant. The base product number TPS62234 covers multiple fixed-output voltage options; confirm the 2.1V variant (DRYR suffix) matches your rail requirement.

Frequently asked questions

What is the switching frequency of TPS62234DRYR?

The switching frequency is 3 MHz. This high frequency allows the use of small inductors and capacitors, reducing the overall solution size.

Is there a pin-compatible alternative to TPS62234DRYR with a different output voltage?

The TPS62234 base product number includes several fixed-output variants (e.g., TPS62230 for 1.2V, TPS62231 for 1.5V, etc.) in the same 6-SON package. Check the TI datasheet for the full list — pinout is consistent across the family, so swapping the voltage variant is a direct board-level change.
