The 1 MHz switching frequency keeps the external inductor small — typically 4.7 µH — which saves board area in space-constrained portable or battery-powered designs. Synchronous rectification eliminates the external Schottky diode, reducing BOM count and improving efficiency at light loads.
The synchronous rectifier helps maintain efficiency across the temperature range without external heat-sinking.
No official replacement order code is listed for the TPS62202DBVRG4. For a pin-compatible alternative within the TPS6220x family, check the TPS62203DBVR (fixed 1.6 V output) or TPS62200DBVR (adjustable output) — verify the output voltage and feedback network against your design. The TPS62202DBVRG4 is obsolete, so a cross-reference to a newer TI part like the TPS62290 or TPS62300 series (different pinout or package) may require a board spin.
