TPS54302DDCT Description

Short technical summary and product information.

The Texas Instruments TPS54302DDCT is a highly integrated synchronous buck converter designed for a wide input voltage range of 4.5V to 28V, capable of delivering up to 3A of continuous output current. This device features internal 85mΩ and 40mΩ MOSFETs, simplifying the external component count and reducing board space.

 

Key electrical specifications include a fixed 400kHz switching frequency, which aids in EMI reduction through frequency spread spectrum operation. It also incorporates Advanced Eco-mode for enhanced light-load efficiency. The converter includes internal loop compensation and a 5ms internal soft-start feature.

 

Protection features include cycle-by-cycle current limit for both MOSFETs, hiccup mode protection for persistent overcurrent conditions, overvoltage protection, and thermal shutdown, ensuring robust operation. The TPS54302DDCT is housed in a compact SOT-23-6 Thin package, suitable for applications requiring high power density and a small footprint.

 

This converter is well-suited for various applications, including 12V and 24V distributed power-bus supplies, as well as industry and consumer electronics such as white goods, audio systems, set-top boxes, DTVs, and printers.
