The TPS54356PWP from Texas Instruments is a high-efficiency, synchronous buck (step-down) DC-DC converter designed for demanding power management applications. This fixed-output regulator delivers a stable 3.3V at up to 3A from an input voltage range of 4.5V to 20V, making it suitable for a wide variety of industrial, automotive, and consumer electronics. Part of the SWIFT™ series, it operates at selectable switching frequencies of 250kHz or 500kHz, allowing flexibility in balancing efficiency and component size. Packaged in a 16-pin HTSSOP (PWP) surface-mount form factor, it integrates synchronous rectification for improved efficiency and thermal performance.
The TPS54356PWP stands out for its high current output, wide input range, and synchronous efficiency, making it a superior choice for space-constrained, high-reliability applications. Its fixed 3.3V output simplifies design while the SWIFT™ architecture ensures fast transient response. Though marked as Last Time Buy, it remains a robust solution for legacy or long-lifecycle projects requiring stable, efficient power conversion. Engineers should evaluate alternatives for new designs but can leverage this IC’s proven performance in existing systems.
