TPS54239EDDA

TPS54239EDDA Description

The TPS54239EDDA from Texas Instruments is a high-efficiency, synchronous buck (step-down) DC-DC converter designed for demanding power supply applications. This adjustable-output regulator delivers up to 2A of continuous output current with an input voltage range of 4.5V to 23V, making it suitable for a wide variety of industrial, automotive, and consumer electronics. The device operates at a 600kHz switching frequency, optimizing efficiency while minimizing external component size. Packaged in an 8-pin SOP (SOPWR) and compliant with ROHS3 and REACH standards, it offers a compact, surface-mount solution for space-constrained designs.

TPS54239EDDA Features

• Wide Input Range (4.5V–23V): Supports diverse power sources, including 12V/24V industrial rails and battery-powered systems.
• Adjustable Output (0.76V–7V): Precision feedback enables fine-tuning for low-voltage logic (e.g., FPGAs, DSPs).
• Synchronous Rectification: Improves efficiency (up to 95%) by reducing conduction losses compared to non-synchronous alternatives.
• 600kHz Fixed Frequency: Balances efficiency and noise, allowing smaller inductors and capacitors.
• Integrated Protection: Includes thermal shutdown, UVLO, and overcurrent protection for robust operation.
• MSL2 (1 Year): Ensures moisture sensitivity compliance for extended storage.

TPS54239EDDA Applications

• Industrial Automation: Powering sensors, PLCs, and motor drivers in 12V/24V systems.
• Automotive Electronics: Infotainment, ADAS, and lighting modules requiring stable low-voltage rails.
• Consumer Devices: Portable electronics, set-top boxes, and IoT edge nodes.
• Telecom/Networking: Point-of-load (POL) regulation for FPGAs, ASICs, and processors.
• Battery-Powered Systems: Efficiently steps down Li-ion or lead-acid voltages to logic levels.
