TPS54302DDCR Description

Short technical summary and product information.

The TPS54302DDCR from Texas Instruments is an EMI-friendly synchronous step-down converter designed for a wide input voltage range of 4.5V to 28V. It can deliver a continuous output current of up to 3A. The device integrates 85mΩ and 40mΩ MOSFETs, internal loop compensation, and a 5ms internal soft start to reduce component count and PCB footprint.

 

This converter operates at a fixed 400kHz switching frequency and incorporates frequency spread spectrum for reduced EMI. It also features Advanced Eco-mode for enhanced light-load efficiency. Protection features include overcurrent protection with hiccup mode, overvoltage protection, and thermal shutdown.

 

The TPS54302DDCR is suitable for various applications, including 12V and 24V distributed power-bus supplies, industry applications like white goods, and consumer applications such as audio, set-top boxes, DTVs, and printers. It is supplied in a SOT-23-THIN (6) package, measuring 1.60 mm x 2.90 mm, making it ideal for space-constrained designs.

 

Key electrical characteristics include an adjustable output voltage range from 0.6V to 26V, a typical quiescent current of 45μA, and a shutdown current of 2μA.
