Texas Instruments SWIFT™ TPS54973PWP is a high-efficiency, synchronous buck switching regulator IC. This adjustable output device delivers up to 9A continuous output current from an input voltage range of 3V to 4V. Featuring dual internal switching frequencies of 350kHz and 550kHz, the TPS54973PWP offers flexibility in optimizing for efficiency or size. The output voltage is adjustable from 0.891V up to 2.5V, with a single positive output configuration. Integrated power MOSFETs and a synchronous rectifier enable high efficiency without the need for an external Schottky diode. Its 28-HTSSOP package is suitable for surface mount applications. This component finds utility in power supplies for networking, industrial, and consumer electronics, particularly in applications requiring compact, high-current step-down conversion.
