The TPS62203DBVT is a synchronous buck regulator delivering a fixed 3.3 V output at up to 300 mA from a 2.5 V to 6 V input rail.
At 300 mA output, the 1 MHz switching rate means the inductor ripple current is manageable with a 4.7 µH to 10 µH inductor. The 3.3 V fixed output suits 3.3 V logic rails, sensor supplies, or MCU VDD — no external resistor divider needed.
