Product details

300 mA buck converter in a 2x2 mm WSON

The Texas Instruments TPS62242DRVRG4 is a synchronous step-down (buck) converter delivering a fixed 1.2 V output at up to 300 mA from a 2 V to 6 V input rail.

Switching frequency and inductor sizing

At 2.25 MHz, the switching period is under 450 ns. That allows inductor values in the 1 µH to 2.2 µH range — small enough for a 0805 or 0603 footprint — while keeping output ripple below 30 mV with a 10 µF ceramic cap. The trade-off is slightly higher switching losses than a 500 kHz part, but for loads under 300 mA the efficiency curve stays above 85% across most of the range.

Housed in a 6-WSON (2x2 mm) with an exposed pad, the part relies on the PCB copper pour under the pad for heat sinking. The 0.50 mm pitch WSON demands careful solder-paste stencil design; a 0.125 mm stencil thickness with a 75% aperture reduction on the pad avoids bridging.

Frequently asked questions

What is the output current of TPS62242DRVRG4?

The rated continuous output current is 300 mA. The synchronous rectifier helps maintain efficiency at light loads, but the 300 mA ceiling is the hard limit for the inductor and switch current.

What is the closest pin-compatible alternative to TPS62242DRVRG4?

No pin-compatible alternative is listed in the available cross-reference data. The TPS62242 family shares the same base number and pinout across output voltage options (fixed 1.2 V, 1.5 V, 1.8 V, etc.), but a different output voltage variant is not a functional substitute unless the load requires that voltage.
