TPS54329DDAR Description

Short technical summary and product information.

The TPS54329DDAR from Texas Instruments is a synchronous step-down DC/DC switching regulator designed for efficient power conversion. It operates with an input voltage range of 4.5V to 18V and can deliver up to 3A of output current.

 

This device utilizes D-CAP2 mode for fast transient response and allows for the use of ceramic output capacitors, contributing to low output ripple. Key electrical specifications include a switching frequency of 650kHz, integrated FETs with low on-resistance (100 mΩ high-side, 74 mΩ low-side), and a typical quiescent current of 0.0008A. It also features Auto-Skip Eco-mode for high efficiency at light loads and a shutdown current of less than 10µA.

 

The TPS54329DDAR is available in an 8-SO PowerPad package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C (TA). The adjustable output voltage can be set from 0.76V to 7.0V, making it versatile for various power supply designs.

 

This component is ideal for applications requiring a compact and efficient power solution. Its features like adjustable soft start, cycle-by-cycle overcurrent limit, and pre-biased soft start enhance its usability in complex designs.
