✅ Original TI TPS54302DDCR, SOT-23-6 package, synchronous step-down DC-DC buck regulator.

✅ Wide input range: 4.5V to 28V, continuous 3A output current, adjustable output voltage down to 0.6V.

✅ Integrated power MOSFETs, internal loop compensation & 5ms soft start, reduce peripheral components.

✅ Built-in spread spectrum frequency modulation, effectively lower EMI interference; support Eco-mode for high light-load efficiency. ✅ Equipped with overcurrent, short-circuit and thermal protection; widely used in industrial control, monitoring equipment and automotive auxiliary power circuits. Datasheet can be provided.
