TPS54202DDCR Step-down DC-DC Buck Converter IC is a high-efficiency synchronous step-down (buck) DC-DC converter designed to deliver up to 2A continuous output current from a 4.5V to 28V input supply. It integrates high-side and low-side MOSFETs, internal compensation, and soft-start circuitry, reducing external components while providing stable and efficient power conversion for industrial, consumer, and embedded applications.
