Product details

DCS-Control buck regulator for 3–17 V rails

The Texas Instruments TPS62125DSGT is a synchronous step-down (buck) converter built around the DCS-Control™ architecture — a hysteretic topology that combines fast transient response with stability without external compensation components.

Switching frequency and output range

Switching at 1 MHz keeps the external inductor and output capacitor small — typical for a 300 mA regulator — while the adjustable output can be set from a minimum of 1.2 V up to 10 V.

Frequently asked questions

Can TPS62125DSGT work with a 12 V input?

Yes. The input voltage range is 3 V to 17 V, so a nominal 12 V rail is well within the operating envelope. The 300 mA output is available across that range.

What is the closest pin-compatible alternative to TPS62125DSGT?

No official pin-compatible second source or cross-reference is recorded for this order code. Within the same DCS-Control family, parts with different output current ratings (e.g., 500 mA or 1 A variants) share the same control architecture but differ in package and pinout — verify footprint compatibility from the respective datasheets before substitution.
